If Obama actually was Israel's enemy, Palestine would already be a full member of the UN and all Israeli settlements (including east Jerusalem) would be illegal under international law. Israel would be in a world of hurt. The UN Security Council would be ramming through all sorts of binding resolutions that would force Israel into a very bad situation. .
You should be very grateful that Obama supports face to face negotiations between Israel and the Palestinians to resolve things instead of an imposed solution from the international community.
