Eighty years ago, a British prime minister stood before the world after meeting with Adolf Hitler and declared there would be “peace for our time.”

Neville Chamberlain’s prediction in 1938, of course, proved to be tragically flawed. World war broke out in September 1939. He was run out of office and has been labeled the world’s most shameful appeaser.

Ladies and gentlemen, I believe today we witnessed a reprise of that moment with Donald J. Trump’s appeasement of Vladimir Putin. Yes, I am going to equate those two hideous examples of weakness.

The president of the United States of America today stood before the world and actually accepted the word of a former KGB spy over the exhaustive work of our intelligence community that the Russians attacked our electoral process in 2016.

Putin said there is “no evidence” of interference. Trump — if you can believe — then denigrated the work of our CIA, the director of national intelligence, the National Security Agency, the FBI, the Department of Justice, which all have said the Russians launched a full-scale attack on our electoral system.

How in the world is history going to judge this shameful exhibition of weakness, of appeasement? The two leaders met today in Helsinki behind closed doors. They faced the international media and then we all heard back here at home our commander in chief give tragically short shrift to this attack on our system of government.

I won’t go as far as former CIA Director John Brennan, who declared Trump’s performance an act of “treason.” I am, however, inching closer to that conclusion.

We have just witnessed a disgraceful display of weakness by the leader of the world’s strongest nation.

Move over, Prime Minister Chamberlain. You’ve got company in the diplomatic hall of shame.
