The US may be the current 'ruling' power of the world, and is constantly attacked. Two hundred years ago, Britain was that power. The only people who know what really happened in WWII, Vietnam, or any other conflict are those who were there. Although debate is a good thing, can we ever answer these questions? Not IMHO. Let's all stop bashing each other over something we can never solve.
As much as I have known, and loved, individuals who are soldiers, sailors and airforce, IMO, the military is a tool of the power brokers of the world, who continue playing their games to see who can get the most profit.
