Close to 2 million people gathered in Paris on Sunday to condemn the murderous attacks on the staff of Charlie Hebdo and on a kosher supermarket that resulted in the deaths of 17 people. One of those attending the march was David Cameron, the British prime minister. Israeli Prime Minister Benjamin Netanyahu as there. So was Mahmoud Abbas, leader of the Palestinian Authority. German Chancellor Angela Merkel and Italian Prime Minister Matteo Renzi were there as well.

Oh, and Jane D. Hartley was there to represent us. Hartley is the United States ambassador to France, and probably known to as many Frenchmen and women as the French ambassador to the United States is known to Americans. You know; whatsisname, Gérard Araud.

But President Obama couldn’t make it. Nor could Vice President Joe Biden. Nor could Secretary of State John Kerry. Apparently nobody from America could make it, so we sent Jane D. Hartley.

And in doing so, Obama revealed an insensitivity not worthy of a world leader. France, after all, is America’s oldest ally, and you just don’t treat old friends quite as shabbily as Obama has with France and its people.

While President Obama may have been too busy to travel to Paris, his counterpart, François Hollande, took the American disrespect gracefully and, speaking through a spokeswoman, declared that he had not been offended. “President Obama supported France in their common struggle against terrorism,” he said.

As though imitating a Ringling Bros. clown stepping into a bucket, Obama caused further embarrassment to himself by giving some of his sharpest critics a free ride for a couple of news cycles.

–Sending Jane D. Hartley to the Paris march was “beyond crass, even for this administration,” said Reince Priebus, the chairman of the Republican National Committee.

–“Our president should have been there,” Senator Ted Cruz wrote in Time Magazine.

–Obama is “a failure when it comes to fighting Islamic jihadists,” said Mike Huckabee.

–“Skipping this rally will be remembered as a new low in American diplomacy,” said Rick Perry.

–“There’s a plethora of people they could have sent,” said Senator Marco Rubio.

They’re right.

No one would remember “Ich bin ein Berliner” if John Kennedy had ordered some deputy assistant secretary of state no one ever heard of to deliver it. Nor would anyone recall “Mr. Gorbachev, open this gate! Mr. Gorbachev, tear down this wall!” if it had been uttered by anyone but Ronald Reagan.

Sometimes the messenger is the message.
