My immediate hot take:

In general, it’s wise to say “We don’t know who did this or why and we shouldn’t speculate until we get all the facts.” In this case we know exactly who did it, and why. The French won’t be talking nonsense about “violent extremism.”

The (obviously) racist French have closed the borders. They are going to (GASP!) profile, to determine who can leave the country. For example, white (and probably many black) Americans will be allowed to leave. Adult male Algerians and Moroccans (and Syrians, to the degree that they’ve been invading recently) not so much.

This was an act of war, and I expect France to treat it as such. Unfortunately, with the apparent collapse of Westphalia, it won’t be obvious who to punish for it, but if ISIS takes “credit” for it, expect them to get a pounding in Syria and Iraq, Russians or no. And unlike us or Israel, the French know they will be immune from charges of “war crimes.”[Update a few minutes later]

Call me nuts, but I’m guessing that France, and Europe in general, is going to be tightening its Syrian-refugee policy as a result of this.

Great timing, Barack: “We have contained [ISIS].” An asshat extraordinaire.

Also, oopsie, more bad timing: Al Gore in Paris this weekend for a summit on the “greatest challenge facing us,” too much plant food in the atmosphere.

Roger Simon: Why Paris happened. Yes, there don’t appear to be any world leaders today, least of all Barack Obama.

Mark Steyn: “The barbarians are inside, and there are no gates.”

And from Richard Fernandez: A Europe with no borders has taken a body blow:

It’s significant that the attacks occurred during a period of heightened alert associated with big soccer matches. French president Hollande himself was watching a game when he had to be unceremoniously shuttled to the safety of a government building. That suggests that French security forces and intelligence were genuinely surprised by the attack and therefore there exist terror networks they don’t know about capable of large-scale operations. Scotland Yard and MI5 must realize this and will inevitably be burning the midnight oil tonight.

DHS should be doing the same thing.

Claire Berlinski checks in from Paris.

“I was wrong“:

I’ve indicated I admire Hof’s honesty and courage in admitting this. But that doesn’t mean I admire everything about him. For example, why didn’t he speak up in September of 2012, which after all was prior to Obama’s re-election? Might it have mattered? I really don’t know, but maybe. And why, oh why, had this very smart man not noticed that the biggest “policy priority” of the Obama administration has long been politics and spinning to political advantage?

Seriously, by March of 2012, how could he have not realized this? His bio doesn’t say much about his political affiliation—I would guess “Democrat” and probably “liberal Democrat”—and this is the most likely explanation for his failure to notice things that were absolutely obvious but would mean splitting with the party.

And there is no more unforgivable thought crime than splitting with the Party, regardless of the damage to the nation
