As an outside viewer , I see that during the last decade Iraq was no threat to anybody , talking nicely on TV , complying with ALL the UN resolutions .
So why now ?
You said it's bec now will be easier than in the future ... That's not a good point and still sounds similar to the preemptive strikes bullsh*t .
I can tell you why now ... Bec Mr. Bush is so happy with his poor victory in Afghanistan (it will never become a complete victory till you get Bin Laden or make sure he's dead) , so he want to try his luck again in Iraq , so he might get a bigger victory , become more popular than ever , wins the next elections ... And wilingly ,his brother takes over from him after that .
He's gotta show the world real evidence to attack Iraq ... Something like discovering a hidden nuke or stuff like that , not sending Mr. Powell to the Security council to hear some clapping here and there.
It's war dude , real innocent people are gonna die there (from both sides) ... So why war for no good reason ?
