Sadly, the wrong country was chosen.
Depends on perspective. Have you ever heard the saying the atomic bombs weren't just dropped on Japan but on Moscow as well?
From the standpoint of State vs State politics, defeating the 4th largest military within 91 days is something that would give the US tremendous deterrence in future potential conflicts.
Which led to much celebration from terrorism recruiters.
Yeah, how did that one work out?
Contrary to popular belief, not sure how this worked out.
There are two levels to this.
--State vs State politics
--State vs Terrorist politics
From the standpoint of State vs State politics, the invasion of Iraq increased America's political power. Basically, States now have to fear US preemptive action if the US has cause, something that until Iraq States did not fear.
From the standpoing of State vs Terrorist Politics... I honestly am not sure.
If I were the leader of Iran, would I be likely to sponsor terrorists now knowing that if something linked directly back to Iran that the US would be willing to invade?
Then the question becomes does that deterrence outweigh the support our operations have given to sub-State terrorist orgs?
The US has not suffered a major attack since 9/11, but would that have happened if we didn't invade Iraq? Will the next terror attack be because we invaded Iraq? It is impossible to say.
Truth be told (because I do try to be truthful in debates) I don't know how it will work out. The Iraqi invasion had "potential" to further US interests and security however we did not execute effectively in terms of "after" the war. As Colin Powell argued vehemently, taking Iraq over would be easy, building it back up and maintaining control after would be very hard. He advised against NOT doing it, but Bush and his croonies overruled him. Then he is quoted with the line, "Iraq is like Pottery Barn, you break it you buy it..." or something to that effect.
I dunno, it's a hard topic to debate mostly because US foreign policy has been so bad for so long...
