Only in Washington could a former Walter Mondale speechwriter who was raised in Canada be permitted to pose as a conservative.

That's Charles Krauthammer, who is seen above making an attack on Ron Paul that is positively bizarre.

Krauthammer is among a group of what I call the "Neo-Cans." There are liberal internationalists who have snuck in from Canada disguised as conservatives. Mark Steyn and David Frum also meet the definition.

In the above clip Krauthammer is asked which of the contenders for the 2012 Republican presidential nomination he could support.

“Probably everyone except Ron Paul, who is living in the 20s, who thinks we can have a moat around the United States and if we ignore the world, the world will ignore us,” he responds.

This is dumb even by neo-Can standards. Of course we can't put a moat around the entire country. How would you dig a moat in the ocean? Doesn't Krauthammer have a map? Most of our borders are already defined by The Atlantic Ocean, the Pacific Ocean and Gulf of Mexico.

As for the two countries with which we have land borders, neither is or ever will be a military threat.

That's just dumb. But that comment about the 1920s is just plain crazy.

Back then there were no nuclear weapons and no long-range bombers. We had a powerful navy to protect our coastlines.

And who was going to attack us? Assuming this neo-Can knows his history - never a safe assumption with neocons - he has to be aware that Germany was in the midst of an economic collapse back then.

And assuming he's aware of that, what would he have had the United States do back then?

Should we have mounted a preemptive strike on Germany before Hitler came to power?

Should we have assembled a fleet and attacked Japan for no reason whatsoever?

Krauthammer is a psychiatrist. And here he is making a real advance in his field. He has provided us with irrefutable proof that neoconservatism is a form of insanity.
