Well, yeah.....that's what "diplomacy" is actually....Tehran is working like crazy to avoid heavy sanctions....and keep the nuke option open to keep invasion at bay.....and U.S. wants to prevent actual nuclear weapons AND delivery systems from coming on line, and keep Israel at bay, Russian is string everyone along to remain a world player, and keep Iran inside the tent pissing out instead of outside the tent pissing in (since Russia actually HAS a border with Iran) Europe is stringing Tehran along to keep the natural gas and heating oil flowing and no more weapons within striking distance of Europe, the Chinese are stringing EVERYONE along in their bid to move up the Superpower of the 21st Century ladder....Israel is stringing U.S. along to keep the money rolling in, and to keep the nukes from falling into Israel while trying to continue to keep the Muslim's outa any power in Israel....keep the heat other places then them and the Palestinians....I think a better question would be...who ISN"T string who along?
