Half a decade or so back, I wrote: “It’s a good basic axiom that if you take a quart of ice-cream and a quart of dog feces and mix ’em together the result will taste more like the latter than the former. That’s the problem with the U.N.”

Absolutely right, if I do say so myself. When you make the free nations and the thug states members of the same club, the danger isn’t that they’ll meet each other half-way but that the free world winds up going three-quarters, seven-eighths of the way. That’s what happened in New York last week. Barack Obama is not to blame for whichever vagary of United Nations protocol resulted in the president of the United States being the warm-up act for the Lunatic-for-Life in charge of Libya. But it is a pitiful reflection upon the state of the last superpower that, when it comes to the transnational mush drooled by the leader of the free world or the conspiracist ramblings of a terrorist pseudo-Bedouin running a one-man psycho-cult of a basket-case state, it’s more or less a toss-up as to which of them is more unreal. To be sure, Colonel Qaddafi peddled his thoughts on the laboratory origins of “swine flu” and the Zionist plot behind the Kennedy assassination. But, on the other hand, President Obama said: “No nation can or should try to dominate another nation.”

Pardon me? Did a professional speechwriter write that? Or did you outsource it to a starry-eyed runner-up in the Miss America pageant? Whether or not any nation “should try” to dominate another, they certainly “can,” and do so with effortless ease, all over the planet and throughout human history.

And how about this passage?

“I have been in office for just nine months — though some days it seems a lot longer. I am well aware of the expectations that accompany my presidency around the world. These expectations are not about me. Rather, they are rooted, I believe, in a discontent with a status quo that has allowed us to be increasingly defined by our differences . . . ”

Forget the first part: That’s just his usual narcissistic “But enough about me, let’s talk about what the world thinks of me” shtick. But the second is dangerous in its cowardly evasiveness: For better or worse, we are defined by our differences — and, if Barack Obama doesn’t understand that when he’s at the podium addressing a room filled with representatives of Iran, Sudan, Saudi Arabia, North Korea, Venezuela, and other unlovely polities, the TV audience certainly did when Colonel Qaddafi took to the podium immediately afterwards. They’re both heads of state of sovereign nations. But, if you’re on an Indian Ocean island when the next tsunami hits, try calling Libya instead of the United States and sees where it gets you.

This isn’t a quirk of fate. The global reach that enables America and a handful of others to get to a devastated backwater on the other side of the planet and save lives and restore the water supply isn’t a happy accident but something that derives explicitly from our political systems, economic liberty, traditions of scientific and cultural innovation, and a general understanding that societies advance when their people are able to fulfill their potential in freedom. In other words, America and Libya are defined by their differences.

What happens when you pretend those differences don’t exist? Well, you end up with the distinctively flavored ice cream I mentioned at the beginning. By declining to distinguish between the foreign minister of Slovenia and the foreign minister of, say, Sudan, you normalize not merely the goofier ad libs of a Qaddafi but far darker pathologies. The day after the president of the United States addressed the U.N. General Assembly, the prime minister of Israel took to the podium, and held up a copy of the minutes of the Wansee Conference at which German officials planned the “Final Solution” to their Jewish problem. This is the pathetic state to which the U.N. has been reduced after six decades: The Jew-hatred of Ahmadinejad and others is so routine that a sane man has to stand up in the global parliament and attempt to demonstrate to lunatics that the Holocaust actually happened.
