President George W. Bush refused Friday to press Israel for a cease-fire in Mideast violence, risking a wider breach with world leaders at a weekend summit already confronting crises with Iran and North Korea. Flying here from Germany, Bush called the leaders of Lebanon, Egypt and Jordan to explore ways to end three days of furious fighting between Israel and Hezbollah militants in Lebanon. Turning aside complaints that Israel is using excessive force, Bush rejected a cease-fire plea from Lebanese Prime Minister Fuad Saniora. "The president is not going to make military decisions for Israel," said White House press secretary Tony Snow. He said it was unlikely either side would agree to a cease-fire now. Snow also said that in his conversation with Lebanon's prime minister, Bush underscored that Israel has a right to defend itself, but should try to limit damage.In Washington, Sen. John Warner (R-Va.), who chairs the Armed Services Committee, urged Bush to "think through very carefully how Israel's extraordinary reaction could affect our operations in Iraq and our joint diplomatic efforts to resolve the Iranian nuclear issue." While making appeals to Arab leaders, Bush did not call Israeli Prime Minister Ehud Olmert. Snow said Secretary of State Condoleezza Rice called Olmert, Palestinian President Mahmoud Abbas, United Nations Secretary-General Kofi Annan and others.
