Barack Obama could have made this argument possibly long before now. Heck, maybe he has.

But now the president says partisan bickering over the merits of the Iran nuclear deal brokered with five other great powers and the Islamic Republic of Iran has gone too far.

He spoke at the Summit of the Americas, where he has made historic inroads in restoring relations with another longtime enemy, Cuba.

Back to Iran.

The deal seeks to scale back Iran’s nuclear development program. It also seeks to prevent Iran from developing an atomic bomb. Republicans universally seem opposed even to talking to Iran about such a deal. Some Democrats have expressed misgivings too. Let’s throw in the categorical objections of Israeli Prime Minister Benjamin Netanyahu and you have the makings of a donnybrook over a critical U.S. foreign policy initiative that in an earlier time might have enabled the president and his loyal opposition to speak with a single voice.

Those days are gone — at least while the current president occupies the White House.

You had The Letter signed by the 47 GOP senators urging Iran to reject a deal, which they stated might not survive once President Obama leaves office on Jan. 20, 2017. Yes, the letter sought to undermine U.S. negotiators.

I certainly understand the need for partisan principle to matter, to count for something. These issues of foreign policy, of difficult and complicated international negotiations need to above that kind of bickering.

Obama’s critics say he is guilty of diminishing U.S. standing in the world. Those very critics are doing that, and more, when they seek to ambush the president while he and his team are working to prevent an enemy nation from developing a weapon of mass destruction.
