Imagine my shock and horror when I read something that came out of Sen. Ted Cruz’s mouth that I found agreeable.

The Texas Republican says the United States should revoke the citizenship of any American known to have taken up arms with the Islamic State of Iraq and the Levant.

Being a fair-minded guy, I want to stipulate that not every loathsome politician is utterly devoid of a good idea once in a while.

Cruz’s notion, as I understand it, is perfectly OK with me.

“There can be no clearer renunciation of their citizenship in the United States, and we need to do everything we can to preempt any attempt … to re-enter our country and carry further attacks on American civilians,” Cruz said.

Amen to that.

I’d like to take that point a step or two further.

First, we should revoke the citizenship of any American known to associate with any terrorist organization. Let’s not limit it to ISIL membership. Al-Qaeda has done terrible things to Americans, as we all know; it, too, has boasted of American-born members, some of whom have been killed by U.S. forces in the on-going war against international terror.

Second, revoking U.S. citizenship of known terrorists removes them from any effort to exempt them from becoming victims of military strikes. I’ve said already that I have no difficulty with American forces killing Americans who’ve taken up arms against their country. Others have questioned the correctness of killing U.S. citizens without giving them “due process.” By my way of thinking, those citizens gave up their rights to due process the moment they suited up in enemy colors.

These so-called Americans have all but renounced their citizenship. Ted Cruz’s idea takes that renunciation a key step further.

Now that I’ve said something in agreement with Ted Cruz, I’ll need some smelling salts.

Still, his idea is on point.
