A good night’s sleep has a way of making one’s perspective change a bit the next day.

It happened to me overnight. I went to sleep wondering why Russian officials are talking about yanking their ambassador to the United States because of our demands that Russia stay out of Ukraine’s internal affairs.

I awoke this morning wondering: Why are we involved in this dispute?

This is a classic United Nations matter that needs to be resolved around the Security Council table of nations — and that certainly includes the United States.

Of all the permanent Security Council members, I’m going to presume that all of them — except Russia, of course — believe fervently in Ukraine’s sovereignty. Therefore, one can presume that the Security Council should be drafting resolutions calling for Russia to back off, get out and leave this Ukrainian matter up to the Ukrainians.

One big problem, of course, with that Russia is one of those nations that can veto anything the Security Council proposes. That makes the matter virtually moot, given the U.N. governing structure.

Still, the United States’s involvement — the demands from the White House and the declarations of “costs” that Russia could pay if it doesn’t butt out — is creating an equally untenable position for this country.

What, precisely, can we do to Russia? We aren’t going to hit them militarily. We aren’t going to sever diplomatic relations; heck, we even had an embassy in Moscow during the depths of the Cold War.

The most we can do is as President Obama has declared: “Stand with the international community” in backing Ukraine’s sovereignty.

Geopolitics remains a highly complicated matter.
