When hostilities have broken out in the past, the usual U.S. response has been an immediate and public bout of diplomacy aimed at a cease-fire, in the hopes of ensuring that the crisis would not escalate. This week, however, even in the face of growing international demands, the White House has studiously avoided any hint of impatience with Israel. While making it plain it wants civilian casualties limited, the administration is also content to see the Israelis inflict the maximum damage possible on Hezbollah.
