Mona Charen: “Does Obama imagine that a deal with Iran and loosening sanctions will further world peace? Just last week, his own administration acknowledged that Russia has been cheating on the Intermediate-Range Nuclear Forces Treaty -- since 1987! Does this revelation dim Obama’s enthusiasm for arms treaties? Does it sober him up? Not a bit. Obama sent President Vladimir Putin a letter, outlining the cheating and -- wait for it -- conveying that the United States is prepared to engage in ‘senior-level bilateral dialogue immediately.’ Not a strong letter. Not even strong letter to follow. There is nothing to follow -- as the world -- and particularly Iran, knows so well.”
