It’s Congress’s fault if there’s a war with Iran, says the White House. Last week administration officials showed their frustration with lawmakers who seek to impose another round of sanctions on the Iranians. "It is important to understand that if pursuing a resolution diplomatically is disallowed or ruled out, what options, then, do we and our allies have to prevent Iran from acquiring a nuclear weapon?" said White House spokesman Jay Carney. "The American people do not want a march to war."
