We've got the troops there already... I absolutely love the preemptive idea. Call it aggression... we are the only world super power... since the beginning of time the most powerful have been able to do what's best for them...now it's our turn.
I don't care who likes us, I don't care about world opinion. Kill any who would aid our enemies. I don't now what the number is, but after we've killed enough, the remaining would be cowed.
Some would argue: but Steve, that will just create more terrorists. Terrorism is here to stay, to one degree or another. Let's start killing all who oppose us, this is our planet to do with what we choose, if we choose.
