Why are conservatives afraid of diplomacy?

JFK once told us the following: We should never fear out of negotiation, but we should never fear to negotiate.
Today, Mark Noonan is telling his conservative bloggers, to hell with diplomacy! Oh, and Obama talking about negotiations with Cuba? He's out of touch with reality and he has no business being running for President.

This is Obama hoping for change - he hopes that if he meets Raul Castro, there will be change. This is an amazingly ignorant view of the true state of affairs in Cuba, where Raul Castro has played the heavy for older brother Fidel for nearly a half a century. Legitimize Raul, and all you’ll do is tighten the shackles on the people of Cuba. It is time, Senator Obama, for Cuba to be free - which means you should agree to meet with Raul only after he’s opened up his nation to the light of liberty.

So when the hell has America become afraid of negotiating with characters we've never really cared for?
Oh, I remember, when President Dumbfuck entered the White House, implemented idiotic policies like Shock and Awe, If you're not with America, you're with the terrorists and closed himself off from any opinion that disagreed with his own until he heard what he only wanted to hear, throwing common sense out the window (along with the Rule of Law, Habeas Corpus, and the Constitution).
I don't know about you, Mark, but I remember when America actually talked to their enemies before we went to war. You should too, since you're hero Ronnie Reagan used diplomacy with the Evil Empire once and again during his two terms as president.
Besides that, our foreign policy of talking tough and threatening to bomb the crap out of other counties is a key factor into why our nation has fallen from grace in the eyes of the world community, you Neanderthal.
