As I have an idea of what you're opinions may be, and why you have them, I will counter, pre-emptively, by saying that the talks with Kennedy and Kruschev were fundamentally different, by context, than talks that may arise between the leader our nation with those of hostile nations in the Middle-East. If you compare our two enemies during these two different times- Russia and any number of countries today (North Korea, Iran, Syria...), Russia was a SUPER-POWER. It was not trying to become one, unlike, especially Iran, who is like a little child playing with his daddy's guns, although they are not exactly guns anymore, but nukes. They NEED to be talked to, because they don't get it. A lack of information to them, will only result in them continuing along a path. If we at least talk to them, perhaps WE can get an idea of just how serious they are, or how far along they are in their convictions, and possibly even ascertain the why. Whatever it may be, It would only be MORE INFORMATION. What is wrong with THAT? The worst that could happen is that we get no new information out of the deal, and then we simply continue along the path of sanctions and such, which we were doing anyway.
The idea that we will legimiate their convictions is such a crock of SHIT. What have they sold you?
