Perhaps forget it is a bad idea.
But being too eager, too impatient, is a bad idea also. Bush said America needs patience - and those are WISE words.

If Bush would just have declared war the very same day the Attacks happened, and nuked the whole Afghanistan, there would\'ve been much more horrifying consequences...
