The US cannot afford another war. Also its blind support for a state that openly defies international law and the basic human rights of the Palestinians diminishes its international standing and its credibility - no one in their right mind could possibly believe that the US is an honest broker in the 'peace process' - it has fostered endless talks and continued illegal settlement. The suggestion that 'facts on the ground' should be recognised has encouraged Israel to continue its land grab and led them to believe that they are invincible - bad policy and extremely counter productive unless you never really intended that Israel would have to make concessions!!!!
