P5+1 talks failed as expected. Washington bears full responsibility. Deal-making isn't at issue. It's portraying Iran as uncooperative for added justification to wage war.
"The six wanted a freeze on Iranian production of uranium enriched to 20 percent purity, which is considered a short step from bomb grade."
In fact, it's a giant one to 90% required for weapons making. It's especially so without intent to produce them.
Medical isotopes and other peaceful applications require 20%. NPT provisions permit it. Iran fully complies. Washington and Israel are serial violators. Their belligerence threatens humanity. Tehran threatens no one.
EU lead negotiator Catherine Ashton said "very intense and detailed discussions (left) significant differences" unresolved. They'll remain so in future meetings. A June 18-19 Moscow one is planned. Nothing substantive will change.
"We will maintain intensive contacts with our Iranian counterparts to prepare a further meeting in Moscow," Ashton announced.
Iran's chief negotiator, Saeed Jalili said:
"Of the main topics in using peaceful nuclear energy is the topic of having the nuclear fuel cycle and enrichment. We emphasize this right."
"This is an undeniable right of the Iranian nation....especially the right to enrich uranium." If P5+1 nations negotiate in good faith, "we will, of course, welcome some offer to cooperate on."
