Of course. It makes perfect sense. Why couldn’t I see it before?

There could never have been a Holocaust had the Jews been armed. Granted, the Nazis swept aside the armies of Poland and France like dandruff, and it took six years for Great Britain — later joined by Russia and the United States — to grind them down. But surely Jewish civilians with revolvers and hunting rifles would have made all the difference.

Much as I’d love to take credit for that insight, I can’t. No, it comes from presidential candidate Dr. Ben Carson in a recent interview with CNN. “I think the likelihood of Hitler being able to accomplish his goals would have been greatly diminished if the people had been armed,” Carson said.

This has become a recurrent theme on the political right, the idea that unarmed victims of violence are to blame for their own troubles. And not just in the Holocaust. Rush Limbaugh said two years ago that if African Americans had been armed, they wouldn’t have needed a Civil Rights Movement. The founder of so-called “Gun Appreciation Day” said, also two years ago, that had the Africans been armed, there could have been no slavery.

There’s more. When nine people recently died at a mass shooting in Oregon, Ted Nugent declared that any unarmed person thus killed is a spineless “loser.” Carson seems to agree. “I would not just stand there and let him shoot me,” he said. Or, as Clint Eastwood says in “Unforgiven” when Gene Hackman complains that he just shot an unarmed man: “Well, he should’ve armed himself…”

It’s so clear to me now. Guns don’t take lives, they save them. Guns make everything better. Carson is a surgeon, not an optometrist, but golly gosh, he’s sure opened my eyes.

As a friend recently observed, what if Trayvon Martin had had a gun? Then he could have killed the “creepy-a— cracker” who was stalking him. Surely, the court would have afforded him the same benefit of the doubt they gave George Zimmerman, right?

And what if the men on Titanic had been armed? That tragedy might have had a happier ending:

LOOKOUT

Iceberg dead ahead!

CAPTAIN

No time to port around it. Get your guns, men! We’re making ice cubes out of this sucker!

KATE WINSLET

Jack, is that a Colt in your pocket, or are you just glad to see me?

LEONARDO DICAPRIO

It’s a Colt, woman. Now, stand aside.

Hey, what if Jesus had been armed?

“Thou wisheth to nail me to what? I think not. Come on, punks. Maketh my day!”

The possibilities are endless. So I’ve taken the liberty of composing a new campaign song for Carson, to the tune of “If I Only Had a Heart” from “The Wizard of Oz”:

When a man’s an empty holster, no courage does he bolster

No confidence is won

What a difference he’d be makin’, he could finally stop his quakin’

If he only had a gun

He could stand a little straighter with that ultimate persuader

And wouldn’t that be fun?

He could put an end to static with a semiautomatic

If he only had a gun

Can’t you see, how it would be?

Woe would avoid his door

The crazy guy would pass him by

Or else he’d shoot — and shoot some more

Oh, the shootin’ he’d be doin’, and all the ballyhooin’

The way the folks would run

His life would be so merry in a world of open carry

If he only had a gun

If you think Carson might like the song, I would not mind at all if you shared it with him: www.bencarson.com/contact.

What’s that? You think I’ve lost my mind? You’re calling me crazy? Boy, that makes me so mad I can hardly control myself!

If I only had a gun…
