Increasing public safety almost always means restricting liberties.

Some will protest that in a world with so much human suffering, it is something between eccentric and obscene to mourn a dog. I think not.

Should we not be moved when it produces a vision—a creature—of the purest sweetness?

Take all your dukes and marquesses and earls and viscounts, pack them into one chamber, call it the House of Lords to satisfy their pride and then strip it of all political power. It's a solution so perfectly elegant and preposterous that only the British could have managed it.

Obama has committed the U.S. to war on the Islamic State. To then allow within a month an allied enclave to be overrun - and perhaps annihilated - would be a major blow.

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

So a Holocaust-denying, virulently anti-Semitic, aspiring genocidist, on the verge of acquiring weapons of the apocalypse, believes that the end is not only near but nearer than the next American presidential election. (Pity the Democrats. They cannot catch a break.) This kind of man would have, to put it gently, less inhibition about starting Armageddon than a normal person.
