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.

THE PRESIDENT: We’re going to do something that’s right. We are talking to the Taliban. We’re talking to a lot of different people. But here’s the thing — because mentioned India: India is there. Russia is there. Russia used to be the Soviet Union. Afghanistan made it Russia, because they went bankrupt fighting in Afghanistan. Russia. So you take a look at other countries. Pakistan is there; they should be fighting. But Russia should be fighting.

The reason Russia was in Afghanistan was because terrorists were going into Russia. They were right to be there. The problem is it was a tough fight. And literally, they went bankrupt. They went into being called Russia again, as opposed to the Soviet Union. You know, a lot these places you’re reading about now are no longer a part of Russia because of Afghanistan.

But why isn’t Russia there? Why isn’t India there? Why isn’t Pakistan there? Why are we there, and we’re 6,000 miles away? But I don’t mind. We want to help our people. We want to help other nations. You do have terrorists, mostly Taliban, but ISIS.
