In another era, an endorsement of a controversial foreign policy agreement by Colin Powell might carry some weight among other members of Powell’s political party.

It won’t this time. In fact, and you might have to wait for it, you well could hear someone suggest that Powell’s endorsement doesn’t matter at all because he endorsed Barack Obama’s two successful elections as president of the United States.

Does it matter, though, that the former secretary of state remains a loyal Republican? Oh … maybe. Then again, maybe not.

Powell said today on “Meet the Press”: “The great concern from the opposition is that we’re leaving open a lane for Iran to create a nuclear weapon in 10 to 15 years. The reality is that they have been on a super highway for the last 10 years to create a nuclear weapon … with no speed limit.”

He said he’s studied the deal in detail, pored over it thoroughly and has concluded that this agreement is better than what we had before, which was nothing.

The retired four-star U.S. Army general and former chairman of the Joint Chiefs of Staff, calls the agreement brokered by the Obama administration a “pretty good deal.”

It’s not perfect, he said. But he’ll settle gladly for a diplomatic solution over a military one.

Given that he’s endured combat — serving two tours of duty as an infantry officer during the Vietnam War — I’ll accept his endorsement.
