Saturday morning, Wisconsin Governor and GOP Presidential hopeful Scott Walker said that he believes the "most significant foreign policy decision of my lifetime" was when President Reagan fired 11,000 striking air traffic controllers in 1981. "It sent a message not only across America, it sent a message around the world," Walker asserted, that "we weren't to be messed with."

That's right: Walker believes that Reagan's union-busting was more important than any other US foreign policy decision since 1967, the year Walker was born. And no, in case you're wondering, this wasn't an accidental gaffe: Walker has repeated this theory multiple times to different audiences. This was just the latest instance. In his book, Walker wrote that Reagan firing the aircraft controllers "not only stiffened the spines of members of Congress, it also stiffened the resolve of our allies, it also encouraged democratic reformers behind the Iron Curtain. It helped win the Cold War."

This is certainly an unusual theory of US foreign policy. But to give it the credit it's due, we've created a handy quiz to help you decide if you agree with Walker's theory.
