Reagan and the 1983 Marines Barracks Massacre in Beirut

Reagan and the 1983 Marines Barracks Massacre in Beirut In 2002, the Presidential Oral History Program at the University of Virginia’s Miller Center of Public Affairs interviewed Caspar Weinberger about the six years (1981-1987) he spent as Ronald Reagan’s Secretary of Defense. Stephen Knott, the interviewer, asked him about the bombing of the U.S. Marines barracks in Beirut on Oct. 23, 1983, which killed 241 Marines. Here’s his answer: Weinberger: Well, that’s one of my saddest memories. I was not persuasive enough to persuade the President that the Marines were there on an impossible mission. They were very lightly armed. They were not permitted to take the high ground in front of them or the flanks on either side. They had no mission except to sit at the airport, which is just like sitting in a bull’s eye. Theoretically, their presence was supposed to support the idea of disengagement and ultimate peace. I said, â€Å"They’re in a position of extraordinary danger. They have no mission. They have no capability of carrying out a mission, and they’re terribly vulnerable.† It didn’t take any gift of prophecy or anything to see how vulnerable they were. When that horrible tragedy came, why, as I say, I took it very personally and still feel responsible in not having been persuasive enough to overcome the arguments that â€Å"Marines don’t cut and run,† and â€Å"We can’t leave because we’re there,† and all of that. I begged the President at least to pull them back and put them back on their transports as a more defensible position. That ultimately, of course, was done after the tragedy. Knott also asked Weinberger about â€Å"the impact that the tragedy had on President Reagan.† Weinberger: Well, it was very, very marked, there was no question about it. And it couldn’t have come at a worse time. We were planning that very weekend for the actions in Grenada to overcome the anarchy that was down there and the potential seizure of American students, and all the memories of the Iranian hostages. We had planned that for Monday morning, and this terrible event occurred on Saturday night. Yes, it had a very deep effect. We talked a few minutes ago about the strategic defense. One of the other things that had a tremendous effect on him was the necessity of playing these war games and rehearsing, in which we went over the role of the President. The standard scenario was that â€Å"the Soviets had launched a missile. You have eighteen minutes, Mr. President. What are we going to do?† He said, â€Å"Almost any target we attack will have huge collateral damage.† Collateral damage is the polite way of phrasing the number of innocent women and children who are killed because you’re engaging in a war, and it was up in the hundreds of thousands. That is one of the things, I think, that convinced him that we not only had to have a strategic defense, but we should offer to share it. That was another of the things that was quite unusual about our acquiring strategic defense, and which now seems largely forgotten. When we got it, we said he would share it with the world, so as to render all of these weapons useless. He insisted on that kind of proposal. And as it turned out, with this cold war ending and all, it didn’t become necessary. One thing that disappointed him most was the reaction of the academic and the so-called defense expert community to this proposal. They were horrified. They threw up their hands. It was worse than talking about evil empire. Here you were undermining the years and years of academic discipline that you shouldn’t have any defense. He said he simply did not want to trust the future of the world to philosophic assumptions. And all the evidence was that the Soviets were preparing for a nuclear war. They had these huge underground cities and underground communications. They were setting up environments in which they could live for a long time and keep their command and control communications capabilities. But people didn’t want to believe that and therefore didn’t believe it. Read the full interview at the Miller Center for Public Affairs.

Exploring the Role of National Culture on Attitudes towards Education Research Proposal

Exploring the Role of National Culture on Attitudes towards Education - Research Proposal Example As the report declares education is the only way to ensure the survival of the civilization, mainly by passing existing knowledge to the younger generations and giving them the capacity to seek further knowledge. However, in the face of globalization, the old methods of transmitting knowledge have become out-dated, especially since the world has become more competitive with the need for people to keep up with changing conditions. These days the world is information-driven and no one can afford to have out-dated information. The United Kingdom emphasises on historical happenings and preservation of cultural values. In the current world, people must be ready to learn from experiences but not to keep looking back at them. All citizens must be involved in the development agenda despite their age, race or gender. This study aims at identifying the cultural values underlying perceptions on education, and making recommendations that would enable stakeholders to work seamlessly for the betterment of the country. The sample will consist of between 120 and 160 secondary schools, only including schools that have data on their student composition, performance, and are willing to give out the data freely. If more schools are willing to provide their data such that it overwhelms the researcher, then random sampling will be employed but taking into consideration the representation of schools and students. This will be the sample for the qualitative part of the study, which will be all about identifying extent, correlations and statistical significance of the interactions of various phenomena under study. The qualitative part of the study will use a cluster sample, and the importance of this sample will be to identify for trends, and look for other

Discourse Analysis Assignment Example | Topics and Well Written Essays - 2750 words

Discourse Analysis - Assignment Example Through investigation of three paradigms: empirical, interpretive and critical, the research uncovered that the dominant discourse is that such bias is not present in the health services sector and that perceptions of discrimination is a product of pre-existing lack of self-esteem and lack of resiliency as a result of cultural inadequacies prevalent in aboriginal cultures. It was discovered that power is maintained in the health sector while deliberate or unconscious marginalization against aborigines dominates the Canadian social and professional sentiment about aborigines. The study concludes that while the researcher has personally observed these biased attitudes, culpability for negative health outcomes on aborigines may be attributable to these populations themselves. Despite the fact that the Canadian health care system provides a legislative framework for ensuring equity of care provision for all members of Canadian society, discrimination seems to be still prevalent in the nursing profession. Bias can be oftentimes observable when providing care to aboriginal members of society, namely against those sharing ethnic characteristics of Indian, MÃ ©tis and Inuit native peoples. Anti-aboriginal discrimination manifests itself through stereotyping, which stigmatizes these society members even in the health care environment. Long-standing stereotypes often portray aboriginals as being pervasive drug users, violent and incessantly unemployed (de Leeuw, Kobayashi & Cameron, 2011). The most prominent label marginalizing Canadian aboriginals is that they are highly dependent on welfare programs and incompetent to the degree that their affairs should be fully supervised by the Canadian federal government (Erickson, 2005). In the health care sector, Canadian aboriginals seek health services, though disproportionate in frequency to non-aboriginal patients.

How Far Can Business Methods Developed In One Country Be Applied In Another :: essays research papers fc

The question states the transferability of business methods from one country to another, via Japanese techniques. However, in order to answer, we must define the term culture, as the term culture encompasses business methods, i.e. in order to adopt foreign business methods we must adopt its culture. In Needle's (1994) definition of culture he states, "A particular interest in business is the extent to which we can learn from the business experiences of other cultures and transplant ideas d eveloped by businesses in one culture and use then in a totally different setting." A major implication of the work of Hofstede (1980) and Trompenaars (1994) and other contributors to the knowledge about international culture and management is that "cultural interpretation and adaptation" are a necessary prerequisite to the comparative understanding of national and international management practice. Hofstede suggests that while 'hard - nosed' (short termist, task/result orientated) American or Anglo-Saxon approachs to business management may work well in Chicago, they may be counterproductive in Japan. More specifically, the procedure of international cultural adaptation may be applied to the three following areas: 1. Motivation theories, 2. Leadership concepts, 3. Management by Objectives (MBO) The three areas are described by Hofstede as symptomatic of the issue at hand. Hofstede states that "not only organisations are culture bound; theories about organisations are equally culture bound." Morden (1993) comments "There is no guarantee, therefore, that theories and concepts developed within the cultural context of one country can with good effect be applied in another. This implies that it is not possible for such theories to be 'universally valid'." In the UK, interest has been awakened by the considerable investment in the economy by major Japanese firms, who have entered certain key industries, such as motor manufacturing and electronics. Whilst taking advantage of investment incentives offered by the British Government, and the range of skills offered by British workers, these Japanese companies (e.g. Toyota, Honda, Panasonic, etc.) have also introduced several of their own personnel and production practices. These have been adapted to achieve the acceptance of the managers and workers concerned, especially in relation to production methods, quality control and management worker attitudes. A comparison between east and west industrial environments can simply illustrate culture differences., In particular, Britain versus Japan. Nevertheless, a number of Japanese management practices have been adopted very successfully in a British context (e.g. Nissan). One of the important general difference between Japanese and British companies lies in the way they are funded.

Orapronobis Case Study Essay

Vigilantes, rebels, ordinary citizens and the government – this is what the film consists of with dry barren lands, unpaved roads and small town as the setting. This is a situation where peace and freedom is difficult to achieve. Nowadays, we are already modernized, living lives in the city and not wondering if this still occurs. Us teens do not really bother what’s with other parts of the country, we only live in a small world, mostly in cyber world but only focusing on entertainment and fun. But does the scene shown in the film really present today? In the story, it was Marcos’ regime when the foreign priest was shot by the so-called orapronobis just because of complaining on what they are doing. At the time martial law ended, our country became democratic and people were non-violent with the lead of Corazon Aquino. That is what everyone thought. But the film just showed me that it is not. It is just orapronobis had been considered vigilantes so the church and the government do not really interfere with their laws and acts even they still kill innocent people. Innocent or rebel, it is still not right to just arrest someone without any proof who they really are as a citizen. Many families had suffered for the loss of a relative especially Jimmy who had been an ex-priest, ex-rebel and advocate for Human Rights, whom his ex-girlfriend back then together with his son got inhumanely killed by Commander Kontra. Now, this moment where Aquino is our president, we do not focus about this matter. We are too busy minding our own lives. There are no news reports about this. But after I had watched the film, I feel a little upset with how our government works. They are too much busy making our country as wealthy as possible not thinking on some poor rural areas where groups such as orapronobis still exist and many men, women and children were brutally killed. I personally did not think that this is still happening but as I had heard on the forum done after the film showing, it really is. It is just media cannot reach this poor areas as well as the government. But it is not right. One’s life is still a life, and it is important. Many lives need justice and these instances needed to stop. I know it is difficult but as this kind of show had been watched by every citizen, there might be some changes. So this must be spread to everyone to make a change!

The Issue Of Equality Within The United States - 1138 Words

Our society has made many steps in the right direction to equality within the last 10 years alone. A few examples being, an African American president, homosexuality in the military, and more recently same sex marriage allowed in all 50 states. Some would say we have made amazing progress with the issue of equality in today’s age, yet there are still many issues proving that we haven’t done our job completely. So with that being said, our government has only protected a limited amount of freedoms. One freedom that is not protected to its extent is Freedom of Religion in schools. Plainview, TX is a perfect example to contribute to this issue. During a recess break in the school day, a 13 year-old boy was caught reading the Bible. It was†¦show more content†¦According to the Texas Association of School Boards, â€Å"Students may pray individually as long as that prayer is initiated by the student and is nondisruptive. A student may pray silently before a test or stop to pray between classes.† This contradicts why Joshua was suspended. He silently read the Bible during his own recess time. Not once had he pushed another student to read along with him or talk about what he was reading. Secondly, a study has recently shown how another issue in society is Gender Equality. According to Huffington Post citing the U.S. Census Bureau, â€Å"Women still earn only 77 cents for every dollar that men earn.† Many would say that equality between men and women has made leaps and bounds of progress, however this statistic can prove that equality between genders really hasn’t come that far. Women once were not allowed in the military, to wear anything other than dresses, and lastly in some states women could not serve on juries. Yes, progress has been made. Yet, in society today women work just as, if not more hard then men at some job places. How come men still earn approximately 23 cents more than women when they are working the same position? It is because women s right for equality has not come to the point it should be in 2016. Huffington Post also states, â€Å"studies show women are paid less even when they are in the same job and have the same
