I think you underestimate what Bush has done. The EU was about to get involved, he preempted that.
He has done nothing to actually stop the Israelies. He knows that information is being gathered which will finish Arafat once and for all.
I noticed that Israel military activity has increased. I think Sharon gave Bush a time-line of what he needs and Bush said 'do it as fast as you can, I will buy you some time'
I think that is what is happening now.
An astute observation and one that I share.
President Bush is walking the tightrope of helping Israel do what it needs and has a right to do while not flatly siding with them 100% in order to maintain at least a flicker of credibility as he attempts to calm EC tensions for a bit while Sharon does what he has to, at least for the short term. The knee-jerk criticism is misdirected, as usual.
