Glenn Grenwald has a post about how an NBC news anchor misrepresented Iran's historic position with respect to nuclear weapons, contrary to Brian Williams' assertion:
To the contrary, Iran has been trying to make Americans hear for years that they have no interest in nuclear weapons. Indeed, they have repeatedly made clear that they have not only banned such weapons but favor region-wide nuclear disarmament, including of Israel's vast nuclear arsenal, which actually exists. It is Israel, not Iran, which has steadfastly refused to allow inspections of its nuclear arsenal (despite UN demands they do so) or to join the NPT or other conventions designed to monitor and regulate nuclear weapons.
But these facts have been excluded almost entirely from the dominant US media narrative for years. The fact that Iran, at its highest leadership levels, has repeatedly and unequivocally disavowed any interest in nuclear weapons is something that most Americans simply don't know,
Well, Brian Williams of NBC isn't the only one pushing this claim about a "suddent" Iranian willingness to resolve disputes with the US. Some guy named Kaveh Waddel writes in The Atlantic:
"Iran’s sudden enthusiasm for negotiation stems from its urgent need for timely, significant changes to the global sanctions regime. But the U.S. lost sight of the power of economic sanctions when it created a regime so inflexible that incentivizing cooperation through sanctions relief became near-impossible."
While the rest of the statement is true -- after all even George Bush II complained "We have sanctioned ourselves out of leverage over Iran" -- the first sentence is definitely false: Iran's desire to negotiate is hardly "sudden" and in fact it has been consistently the case for over a decade now. Iran has been making compromise offers, Iran offered to ship out its enriched fuel and Obama killed that, Iran suspended enrichment for close to 3 years whilst in negotiations with the EU-3. There's nothing "sudden" about this at all. In fact it is pretty much the definition of NOT sudden.
