The only one of those I meant to do was the third, but what the hell. Glenn's post is just fascinating: He mischaracterizes what I wrote, misstates a pretty basic fact about America's ongoing wars, misrepresents Eugene Volokh, and engages in an elaborate misdirection by focusing on a side issue ("wars initiated essentially on presidential whim") rather than the meat of the old quote of his that I posted at Hit & Run ("so many foreign troop deployments that even military buffs can't keep track of them all"). Read the quote's context, and you'll find plenty about the dangers of "imperial ambitions" and "foreign entanglements" -- and absolutely nothing about whether those wars were authorized by Congress. But that's where he focused his response.
The weird thing is, I didn't even intend my original post as a potshot. I guess you never know what's going to set someone off. People sometimes call Glenn the Blogfather, but if this were a gangster movie I'd say it was more Scorsese than Coppola -- call it Blogfellas. "Hey Glenn, isn't it funny that you used to write things like this?" "Funny how? What's funny about it?...Funny like a clown? I amuse you?"
