Why would the ragheads be escalating now, given that the US has its troops in the field and looking for trouble?
Together with the increased atrocities against civilians, it is an increase in the intensity of the provocation. They are trying to draw us in, or draw the Israeli army into action. Why?
One can only speculate, but it feels to me like an overall plan is being enacted, with the goal perhaps of dealing a decisive blow. That can only mean use of some kind of WMD, here or in Israel.
Perhaps this what GW meant when he said "Time is not on our side." Perhaps this is why Sharon is biting the bullet day after day. They must know something is afoot.
The end result will be holocaust for the barbarians, but they already have shown scorn for life itself, and at what cost to civilization?
I mean, it's no fun blowing yourself up outside the fence..
