You'd have thought that the CIA would have learnt from training and arming a chap named Ho Chi Minh and his mates to help liberate French Indochina from the Japanese back in the day.
Virtually every single place the US has "intervened" to replace/attempt to replace the current ruler/leadership since 1945 has blown-up in their face, literally in some cases. Worst is that the tactics that failed 50+ years ago are still being used right now and are still failing, it's a joke!
I mean this is a quick list of some of the dodgy crap the CIA was upto in the first 15 years post WW2 -
1945-1949 - China - armed anti-Mao rebels, gave Mao a reason to invade North Korea later on prolonging the problems there and solidifying Mao as the supreme leader and bringing the CCP to power.
1949 - Syria - helped a military dictator overthrow the democratically elected leadership - 2 weeks later a new oil pipeline deal signed.
1950-1953 - Burma - as a way to attack China, the US staged attacks from Burma, trading weapons for drugs to keep the people smuggling supply routes open.
1952 - Egypt - helped plan the coup which overthrew the Royal family and replace them with military dictators who then attacked Israel twice.
1952 - Iran - again helped plan the coup which overthrew the Royal family and replace them with military dictators, directly leading to 1979 revolution.
1954 - Guatamala - AND AGAIN, helped plan the coup which overthrew the democratically elected leadership and replace them with military dictators.
1956 - Syria - a second coup planned and attempted to replace the people who kicked out the leadership from the 1st CIA coup back in 1949.
1957 - Indonesia - plotted and attempted a coup against the democratically elected leadership, including committing war crimes by deliberately targetting foreign civilian commercial ships.
1959 - South Vietnam - Well we've all seen where this ended up haven't we, however the start isn't anywhere near as a well known but, as usual, the US started it's own quiet war against the North and by 1963, when that quiet war wasn't going it's way, planned and aided in the coup which allowed the US to be fully dragged into a much wider war whose end we all know.
