As for that article in the Post, it has been well dissected here on FR. I don't doubt that the people who are sending anthrax out are HERE - but I also don't doubt it will be linked back to al Quaeda.
The people of Afghanistan have some amount of self-determination. The Taliban didn't spring up out of thin air. You may think it cavalier to bomb the people of a nation with which we are at war, but it is an unfortunate necessity sometimes.
Let me leave you with a quote from General William T Sherman:
You cannot qualify war in harsher terms than I will. War is cruelty, and you cannot refine it; and those who brought war into our country deserve all the curses and maledictions a people can pour out. I know I had no hand in making this war, and I know I will make more sacrifices to-day than any of you to secure peace.
You make my point for me A state of war has not been declared! The Constitution of the US is still in effect, unless somethings changed while I wasn't looking. Artcle 1 Sec 8 gives the Congress the power to declare a war, which they have not!
