Now it’s the allies who are weighing in with criticism of the Republican Gang of 47’s letter to Iran.

Our nation’s European allies have chimed in with a blistering critique of the Senate GOP letter that says it’s OK for Iran to ignore whatever treaty that’s negotiated to get rid of Iran’s nuclear program.

“Suddenly, Iran can say to us: ‘Are your proposals actually trustworthy if 47 senators say that no matter what the government agrees to, we can subsequently take it off the table?’ ” German Foreign Minister Frank-Walter Steinmeier said during a visit to Washington.

What’s Germany’s stake in this? The Germans, along with the United States, Great Britain, France, China and Russia are negotiating with the Iranians for a way to rid the Islamic Republic of its nuclear ambition.

A large portion of the U.S. Senate’s Republican caucus has decided to take matters into its own hands by seeking to persuade Iran to ignore whatever agreement is worked out. Without congressional approval of a treaty, the Gang said, it becomes merely an executive agreement that can be wiped out when the next president takes office in January 2017.

Technically, it’s true. But the letter constitutes an egregious interference in a high-stakes negotiation.

Welcome aboard the criticism train, allies.
