It's hard to remain neutral when we are pretty much the only superpower left, and honestly I wish a lot of times we weren't. Every time something happens somewhere everybody turns, looks at us and says 'Well? What are you going to do?'. We send in troops, some eggs get busted, now we are the scum of the earth once again. Then something else happens, everyone looks at us and says 'Well?'...
It's also time for a history lesson too.
The Japanese were buying oil from us in the 1930's. Yeah, at the time we were sort of like Saudi Arabia. Anyway, they decided they wanted pretty much all of Asia and proceeded to invade China among other places. The reports of brutality coming back (the 'Rape of Nankang' in particular) prompted Congress to cut off oil sales to them and THAT is what triggered WWII.
There was no 'ayatollah to turn over to Iran'. There was a Shah of Iran who was deposed by his own people. He did NOT come to the US, instead he was granted asylum in Egypt by Anwar Sadat. The Ayatolla Khomeini was the 'leader in exile' of the opposition which overthrew the Shah and he was running the whole thing from Paris, France. The US had for many years supported the Shah over oil sales. THAT was where we went wrong. Why did we not overthrow him? What, depose the leader of a sovereign nation? Not supposed to happen. Besides, the last time we had tried to get involved with that type stuff was in South America in the 1950's and that did not go well at all.
Vietnam was known as French Indochina at the turn of the 20th century, it was a French colony/protectorate. Things were not going exactly smoothly, then during WWII the Japanese invaded and occupied the country. (See how this ties into the China thing above?) Ho Chi Minh was the leader of the forces trying to throw the Japanese out, at the end of WWII France reasserted control of French Indochina and Ho Chi Minh turned to attacking the French. In 1954 as part of the Geneva Accords France relinquished their claim, Laos and Cambodia became independent kingdoms and Vietnam was split into North and South. So the French were gone long before we ever got involved. How did we get stuck in the mire? North Vietnam was Communist, South Vietnam was not. North Vietnam invaded South Vietnam and the South Vietnamese government requested our help (see the pattern here?), we first sent advisers then troops as things escalated.
Support Castro? Castro (along with Che Guevera) was already in bed with the Soviet Union; remember this was at the height of the Cold War. Such a thing was unthinkable. Batista was a corrupt sonofabitch with strong ties to the Mafia, also remember I mentioned above things had not gone well in our South America interventions? That was still real raw and fresh so we took a 'hands off' policy until after things were settling down. Batista fled to Portugal so was not being held or protected here. Kennedy tried to assassinate Castro (that's proven) so obviously he had not listened to the advisers who were familar with the earlier South American fiascos. Thanks to the assassination attempts and the Bay of Pigs Castro embarked on a lifelong quest to embarrass the US whenever he got the chance, starting with the Soviet missile crisis.
So there you have it: correction of the inaccurate depiction of history in this thread and also support for a policy of US isolationism. We are steadily becoming energy independent; IMHO once that's done we need to shut down every military base not on US soil, bring all our troops back home and fix our problems here while giving the rest of the planet the finger; they can fix their own damn problems.
