Trump’s Cracked Afghan History

His falsehoods about allies and the Soviets reach a new low.

President Trump’s remarks on Afghanistan at his Cabinet meeting Wednesday were a notable event. They will be criticized heavily, and deservedly so. The full text is available on the White House website.

Mr. Trump ridiculed other nations’ commitment of troops to fight alongside America’s in Afghanistan. He said, “They tell me a hundred times, ‘Oh, we sent you soldiers. We sent you soldiers.’”

This mockery is a slander against every ally that has supported the U.S. effort in Afghanistan with troops who fought and often died. The United Kingdom has had more than 450 killed fighting in Afghanistan.

As reprehensible was Mr. Trump’s utterly false narrative of the Soviet Union’s involvement there in the 1980s. He said: “The reason Russia was in Afghanistan was because terrorists were going into Russia. They were right to be there.”

Right to be there? We cannot recall a more absurd misstatement of history by an American President. The Soviet Union invaded Afghanistan with three divisions in December 1979 to prop up a fellow communist government.

The invasion was condemned throughout the non-communist world. The Soviets justified the invasion as an extension of the Brezhnev Doctrine, asserting their right to prevent countries from leaving the communist sphere. They stayed until 1989.

The Soviet invasion of Afghanistan was a defining event in the Cold War, making clear to all serious people the reality of the communist Kremlin’s threat. Mr. Trump’s cracked history can’t alter that reality.
