To go into Ukraine and to take over, to invade Crimea, is a huge step. And [Russian President Vladimir Putin] would only have done it with a president who has shown from the very beginning that [President Obama] is living in a fantasy world...They imagine the world as a new interconnected world where climate change is the biggest threat and they are shocked that the Russians actually are interested in territory.

Hawks favor war on the grounds that Saddam Hussein is reckless, tyrannical and instinctively aggressive, and that if he comes into possession of nuclear weapons in addition to the weapons of mass destruction he already has, he is likely to use them or share them with terrorists. The threat of mass death on a scale never before seen residing in the hands of an unstable madman is intolerable – and must be preempted.

Preemption is a kind of pre-deterrence that stops the threat at an earlier, safer stage.

This week, Iranian-backed Houthi rebels seized control of the Yemeni government, heretofore pro-American. In September, they overran Sanaa, the capital. On Tuesday, they seized the presidential palace. On Thursday, they forced the president to resign.

Why should we care about the coup? First, because we depend on Yemen's government to support our drone war against another local menace, al-Qaeda in the Arabian Peninsula (AQAP). It's not clear if we can even maintain our embassy in Yemen, let alone conduct operations against AQAP. And second, because growing Iranian hegemony is a mortal threat to our allies and interests in the entire Middle East.

In explaining any puzzling Washington phenomenon, always choose stupidity over conspiracy, incompetence over cunning. Anything else gives them too much credit.

Where religion is trivialized, one is unlikely to find persecution.
