"We the People," collective guilt, and Original Sin

Iraq, Iraq, Iraq, 911, 911, 911! War is hell!
I feel for the people but the gov had to be dealt with.
Just like the British. The Iraqi people weren't wrong but their leader/s had us in the position of feeling threaten and needed to be removed.
What would others have done in the wake? Everytime I ask the question it doesn't get answered...

At some point our gov must adhere to "to provide for the common defense!" or contest that portion of the constitution?
