Describe the effects of these diplomatic efforts for the U.S. and other countries. Assess, in conclusion, the advantages and disadvantages of the particular doctrine that was followed
The major advantage of Reagan's foreign policy was the end of the Cold War and freedom for millions of people previously trapped behind the Iron Curtain. I have to confess that I never imagined that I would see the fall the Iron Curtain in my own lifetime. It was astonishing to see how quickly it happened when it did finally happen. Reagan may have been one of the few people living in the U. S. in the early 80s who actually believed that communism would collapse.
Another disadvantage is that policies such as our support of the fighters in Afghanistan created possibilities for "blowback" as people armed by the United States did not necessarily share the interests of the United States beyond resisting Soviet influence. Another example would be US support for both sides, but especially Iraq, in the Iran-Iraq war. One might also argue that it perpetuated, even added to, a military-industrial complex that soaks up billions in budgetary spending. Then, of course, there was the fact that American money and weapons went toward killing people around the world, which scarcely enhanced the image of the country.
The major drawback of Reagan's "doctrine" was that it antagonized some other countries because it seemed like "cowboy diplomacy." However, any sort of forceful action will antagonize someone. It is hard to please all the people all the time.
To start with, Reagan is most well known for his diplomtic dealings with Soviet Union. He was known for his hardline rhetoric and his firm dealings with then Soviet leader Gorbachev. He also used the economy of the U.S. to cripple the Soviet economy by increasing military spending. This sudden rise in arms was tough for the Soviet's to follow, and strained their economy. This apporach to Cold War politics helped cause the fall of the U.S.S.R. to some degree.
