Another's wrong does not justify the commission of a wrong. But in all those instances that the US has been gung ho the US did not annex any of those countries. Russia on the otehr hand invades to add to their territory, worse they invade their neighbors that they call brothers... But for a closer look at your list: 1. Iraq - We'll after Iraq (Saddam) invaded Kuwait it has become a clear danger to its neighbors. Practically everybody from Iran to Saudi to minorities within Iraq wants (privately, publicly they were against American meddling in the region) the US to remove Saddam. In fact the biggest beneficiary of the removal of Saddam is? Yes, Iran. 2. Libya - It was the French that spearheaded the effort to remove Gaddafi. The Americans simply went along with it. 3. Vietnam - It was the height of the Cold War between the US and USSR. The Americans mistakenly thought they were containing the spread of communism in Vietnam when in fact they were fighting an independence movement. 4. Korea - The same, it was the start of Cold War and naturally the Western powers will resist and advance of communist regimes. And knowing now how crude, pathetic, unstable and dangerous the Kims' cult in North Korea has grown I think Asia owes the US and UN a lot for containing North Korea. 5. Iran - The US did not invade Iran. 6. Afghanistan - What would you want the US to do when Afghanistan's Taliban was protecting Al Qaeda as the latter plots and executes terror operations in America? You'll be the most irresponsible American leader if you do not act to neutralise Al Qaeda in Afghanistan seeing what happened in 911 when you have the capacity to do so (but I doubt you care about 911, you might be one of those who believes that it was a false flag ops of the CIA). 7. Serbia - Again, what will America do when Europeans cannot stop the genocide that is happening in Europe? Help. Blame it on Melosevic and Mladic why the Western powers have to intervene in Serbia. Anyway, you seem to be carrying a lonely crusade here since even Serbians seem to agree with the actions of the Western powers against Melosevic in the 90's as Serbia is now set to join the EU.
