John Bolton, former U.S. ambassador to the U.N., was on “The Kelly File” tonight to discuss the crash of Malaysia Airlines Flight MH17.

Bolton said the tragedy “should be a wakeup call,” not just in the conflict in Ukraine but overall in terms of what Russia’s been up to. He called on America, Europe and NATO to go well beyond adjusting the sanctions policy, and said we should reestablish missile defense programs in Poland and the Czech Republic.

“We’ve got to begin to treat Russia like the adversary that Putin is currently demonstrating it to be,” he said.

While Bolton said no one could have foreseen this specific tragedy, he said, “It is entirely understandable that something like this has happened because of the way Putin has perceived American weakness. And I think we’ve gotta change both the reality and the perception of that, we need to bring the Europeans along, we need some leadership. I don’t see it at the moment.”

“This has been a policy of appeasement,” Bolton told Megyn Kelly.
