ON THE EVE of his meeting with President Bush today, Crown Prince Abdullah of Saudi Arabia warned of “a strategic debacle” that could result in the Saudis employing “the oil weapon” against the United States and demanding that U.S. forces leave their bases in the Kingdom. Although the ostensible cause for these threats is the Bush administration’s support for Israel’s actions against Palestinian terrorists, the Saudi ruling family clearly has been unnerved by the president’s commitment to win the larger war on terrorism in the region.
