World leaders usually say they are leaving “all options on the table” when dealing with crises.

President Obama, though, has taken another — quite reasonable — approach in trying to find a solution to the crisis in Ukraine.

He has ruled out a “military excursion” pitting U.S. armed forces against Russians.

Good call, Mr. President.

The United States does not need another war. It certainly does not need a shooting war with Russia, which — in case anyone needs reminding — is the second-greatest nuclear power on the planet; the United States is No. 1, but the Russians still have the ability to inflict cataclysmic damage.

Thus, the United States will not entertain the idea of engaging Russia on the battlefield.

Critics no doubt will say something about a “timid” U.S. response that “emboldens” Russian President Vladimir Putin. Let them grumble.

The very idea of a U.S.-Russia battlefield confrontation is too chilling to even ponder, let alone discuss out loud.
