It doesn't matter whether we reverse EVERY foreign policy decision this country has made in the past century. It doesn't matter if every single American troop was off foreign soil. The Islamic-terrorists are looking for parity. Ayman al-Zawahiri is on the record as having said:
"We have not reached parity with them. We have the right to kill 4 million
Americans - 2 million of them children - and to exile twice as many and
wound and cripple hundreds of thousands. Furthermore, it is our right to
fight them with chemical and biological weapons, so as to afflict them with
the fatal maladies that have afflicted the Muslims because of the
[Americans'] chemical and biological weapons."
