Newt Gingrich followed Bill O'Reilly's lead last night on The O'Reilly Factor, talking about how Americans' drug use -- and not horribly wrong-headed American drug laws -- are responsible for the border wars being waged by Mexican cartels.

O'Reilly seemed to think that Singapore might be a model to follow, since things work so swell over there:

O'Reilly: I don't know whether you know this, but I did one of my papers at Harvard on this -- on how to reduce demand for drugs. But the United States has never figured it out. You can't lock up drug users, I mean, that doesn't work. And you can't force them into rehab, you have to want rehab, and even if you want it, it's very hard to get off hard drugs and alcohol. Very hard.

What you can do, though, is sanction people along the way. And this is what they do in Singapore. If you're caught possessing drugs -- and that means drugs in your bloodstream, they have a little hair thing, and they put it in there -- then you have to go to mandatory rehab. And they have centers where you go.

Now, they have no drug problem in Singapore at all, number one, because they hang drug dealers -- they execute them. And number two, the market is very thin, because when they catch you using, you go away with a mandatory rehab. You go to some rehab center, which they have, which the government has built.

The United States does not have the stomach for that. We don't have the stomach for that, Mr. Speaker.

Gingrich: Well, I think it's time we get the stomach for that, Bill. And I think we need a program -- I would dramatically expand testing. I think we have -- and I agree with you. I would try to use rehabilitation, I'd make it mandatory. And I think we have every right as a country to demand of our citizens that they quit doing illegal things which are funding, both in Afghanistan and in Mexico and in Colombia, people who are destroying civilization.
