The problem is that if you believe that USA is the one with "the mission" then if terrorism appears in some way here for example that will justify the invasion and the killing of many innocents. Then they will say "but those civilians were supporting the terrorists". Do you see my point? With the military support and expansion that USA already has in all the world it can do this with the lower of difficulties.

I don't know about the reduction of terrorism i should look for statistics on that, but you can't be sure on the decrease of terrorists.
And i do believe that any given economy allied to another is beneficial to any nation. Besides winning on Iraq meant that Kuwait will never be under menaze again, therefore that assures the oil.

Someone above mentioned some evidence of zero link between Iraq and terrorism. How can it be that there's such a different perception of one single truth? We are not talking about colors, we're talking about a simple fact. Was there terrorism or not?
