The latest failure of talks between Iran and the six world powers represented by Catherine Ashton — the United States, Russia, China, France, Britain and Germany (the five permanent members of the U.N. Security Council plus one, respectively) — indicate that unless a new approach is tried, further talks will be futile and will only increase the animosity between both sides.

"The time has come for the world to take a tougher stance and make it clear to Iran once and for all that these negotiation games are approaching an end," said Israel's Strategic and Intelligence Affairs Minister Yuval Steinitz in a communique.

Steinitz, a close ally to Prime Minister Benjamin Netanyahu, told Israel's Army Radio that stronger action should be taken within a few weeks or a month to persuade Iran to halt its uranium enrichment activity.
