"Bomb North Korea, Before It’s Too Late."

That's the title of an op-ed in the NYT by a Jeremi Suri, a history/public affairs prof. ("The Korean crisis has now become a strategic threat to America’s core national interests. The best option is to destroy the North Korean missile on the ground before it is launched. The United States should use a precise airstrike to render the missile and its mobile launcher inoperable. President Obama should state clearly and forthrightly that this is an act of self-defense in response to explicit threats from North Korea and clear evidence of a prepared weapon.")

And here's Rush Limbaugh, a couple days ago: "Folks, we have discovered the missile silos in North Korea. We know where they are. My question is, why are they not rubble? If we know where they are and we haven't taken them out, what is this automatic assumption that if they launch, we are going to obliterate their country? Do any of you believe that would happen? I'm serious. North Korea launches nukes at us. They can't hit us yet, so they fall whatever hundreds, thousands of miles short. But the intent was clear. You think we'd retaliate?"
