The power is there, they just don't want to pay the cost in terms of money, lives, and polling popularity. This was done on the whim of a man-child throwing a tantrum, backed by his deeply racist hatred towards Obama. There was no plan other than his usual bullying tactics. Don't get me wrong, I'm glad we are not investing insane amounts of money and large lives into this, but we absolutely could win this if we wanted to pay the cost.
