In 2007, having been presented with evidence that Syria was building a nuclear reactor in the town of al-Kibar, President George W. Bush told the Israeli prime minister Ehud Olmert that not only would the U.S. not take action, but he expected Jerusalem to show restraint. Olmert nonetheless ordered the daring air raid that destroyed the site. In his book on the episode, Yaakov Katz notes that, after learning of the operation, Bush did not reprimand Olmert but instead offered his support in the event of a Syrian response. Michael Doran writes in his review:

According to the Lebanese government, the explosion in its capital city on Tuesday that left over 100 dead and many more injured or homeless was caused by the accidental detonation of some 2,750 of ammonium nitrate, a fertilizer often used for making bombs. (Less than one-thousandth of that amount was used by Timothy McVeigh to destroy the Oklahoma City federal building in 1995.) Previously, police have discovered Hizballah warehouses in London and Germany storing many tons of the same explosive. Hussein Ibish comments:
