U.S. President Joe Biden on April 12 said he expected Iran to attack Israel "sooner, rather than later" and warned Tehran not to proceed. Asked by reporters about his message to Iran, Biden said simply, "Don't," and he underscored Washington's commitment to defend Israel. "We are devoted to the defense of Israel. We will support Israel. We will help defend Israel and Iran will not succeed," he said. Israel braced on April 12 for an attack by Iran or its proxies as warnings grew of retaliation for an attack on Iran's embassy compound last week in Damascus.
