I wouldn't go that far to agree with your statement after all they are politicians and without a peaceful resolution formatted by the administration up front it could create a worldwide hatred for the US and Israel even worse than what exists now.
Politically, it is the right thing to do I.E. the roadmap....then squash the terrorists when THEY break treaty!
I hope there is at some level a realization that the time for this will come. Perhaps when the world is awash with oil we can clean up the nests of terrorism. Until we are truely ready for a serious religious war, we should prepare.
