The guy's name is Nguyen Van Thieu, he was president of South Vietnam from 1965-1973. He was very much a dictator and suppressed any dissent against him during the Vietnam War, and pretty much the only reason he became president was because he was anti-Communist, and the US liked that.
I would not say that we installed Thieu, rather we backed his government due to its anti-Communist fever and war against the Communist North. I believe it was actually the French that orchestrated his rise to power, but I may be mistaken. I would use the term "propped up" his government over "installed".
And yes he was assasinated.
Also, Kestrel, all the nations you mentioned their leaders were not installed by the US, rather they were once friendly nations whose governments we supported for a variety of reasons. If there is a leader that comes close to being installed it would be Hamid Karzai, but even at that he has been elected by his own people.
