Bullcrap. Obama always uses the cheap debate trick of the false dilemma. Either take this deal or bomb tomorrow. The only reason they came to the table was they are hurting from sanctions. Obama eased them just for talking, and refused to consider upping the pressure. Donald Trump is exactly right in saying that’s negotiating from a position of weakness, something you should never do. He’s also right saying we should have walked out when Khameni rubbed it in Obama’s face by leading a death to America rally. If they are serious about a deal they would come back with an offer, if not, well then you know. If you remember the Russians walked out of the SALT talks when Reagan deployed missiles in Europe, and came crawling back when it failed.
What “we” want and need is radically different from what the Sultan in Washington wants and needs.
Actually the second SALT treaty was signed by Carter and the Soviets in 1979 a year before Reagan was elected.
I think you're referring to the Intermediate-range Nuclear Forces (INF) negotiations, that began in 1983 and the subsequent treaty that Regan and Gorbachev signed in 1987.
That treaty has been mostly scrapped on both sides.
