For conservatives and Republicans who are wondering what in the world happened to their party, we should recall June 12, 1987.

That day, 21 years ago, President Ronald Reagan stood before the wall dividing East and West Berlin and directed his famous appeal to the leader of the then Soviet Union, “Mr. Gorbachev, tear down this wall.”

The rest, as they say, is history. Two and half years later, the wall was down and a new chapter begun.

It’s always worth recalling Reagan’s courageous act and words of that time. But we particularly should consider it now in light of today’s Republican conundrums.

I turn to the well-known account of Peter Robinson, then a Reagan speechwriter, of how it all came about.

The story of Reagan’s Berlin speech, as recounted by Robinson, is about change and fighting the Washington establishment - exactly the themes we’re hearing almost every day now from our current presidential aspirants.

Robinson wrote the speech for President Reagan, including the famous “tear down this wall” line, and submitted it for review. The opposition to it from the administration’s entire foreign policy establishment was uniform and adamant.

The National Security Council and the State Department were opposed, as was our highest-ranking diplomat in Germany. They felt it was too provocative and unrealistic.

“Well, there’s the passage about tearing down the wall,” Reagan said. “That wall has to come down. That’s what I’d like to say.”

Seven drafts later, the establishment was still trying to purge the speech. Reagan was on Air Force One, en route to Berlin, when there was a last attempt to block it. But the speech was delivered, including the historic line, which stayed in, according to Robinson, “solely because of Ronald Reagan.”

Reagan’s leadership established the Republican brand in the 1980s, which kept it in ascendancy throughout the ’90s, even through Clinton’s presidency, when Republicans captured the House. Continued...
