Years ago George Carlin joked, "I think we should attack Russia now. They'd never expect it!"
Younger readers, and Democrats with memory problems, might not understand why that joke used to be funny, but at the time it got a huge laugh from the audience. The Cold War had been over for a long time, things had cooled off between the two nuclear superpowers, and Russia had ceased to be a major concern. The idea of wanting to return to the decades of Cold War terror where everyone lived in constant fear of nuclear annihilation was so absurd that you could get people rolling in the aisles with laughter at the suggestion.
And now we have a leading presidential candidate who is already actively trying to bring us back there. She's not even making a secret of it. She's been flat-out telling us, with her own face hole, that she wants to impose a no-fly zone on a nation where Russia is conducting aerial military operations. That's the stated agenda of a candidate who WikiLeaks revealed maintains "both a public position and a private position" on policy. Her stated agenda is to immediately start shooting down the military planes of a nuclear superpower. I don't even want to think about what her private position might be.
