If Palestinians were to unilaterally declare a Palestinian State, and Israel were to carry out your plans in response, without regard for international law, the UN, international criminal jurisdictions, and the international community, Israel will experience the wrath of the world as it has never before imagined. It will see the withdrawal of all US support, and without the US veto, Israel will be dragged before the Intl Criminal Court in the Hague so fast it will make your head swim. No longer will there be US financial support, international loan guarantees, support in the World Bank, or the IMF. With the world-wide sanctions, divestments and boycotts that would follow, Israel would be completely isolated from in the world community of nations, no imports, no exports, no international associations, no loan guarantees, no military support: and Israel would not survive such isolation. President may recognize a new state without congress, as Truman recognized Israel.
