In fact you did insinuate it by the above statement. And you can call it whatever you want, however Constitutionally there was never a formal declaration of war. Just passage of an open-ended statement giving the executive branch the supposed power to wage 'war' on any number of enemies at some point in the future. Of course there hasn't been an official declaration of war since 1941. Look to WWII and even WWI for official declaration of wars
In case you didn't know, the Islamo-terrorists declared war against the United States way before 9/11.
That's a maybe. However none of these 'Islamo-terrorists' came from Iraq. The main purpose of the police action in Iraq (according to the executive branch and most of the MSM which is now maligned here) was the issue of WMDs, of which none have been found
