We should have probably hit Iraq harder and wiped out Suddam Hussien at the time we were there. We should probably not have sided with the KLA in the Serbian situation. We could have perhaps gone in with NATO AND the Russians to end the hostilities between the two factions.
Mistakes were made. Hindsight is always 20/20. BUT, none of that compares to what those raving lunatics who consider themselves blessed by Allah did yesterday. We didn't deliberately kill (or try to kill) 50,000 innocent souls and then deny we did it. We did what we did to maintain some semblence of stability to regions that are crucial to not just our own security, but that of the World.
Although on principle I've agreed with what the Libertarian candidate may have said in the past, I'm glad he didn't get elected.
