When Israel launched its series of strikes against Iran last week, it also issued a number of dire warnings about the country’s nuclear program, suggesting Iran was fast approaching a point of no return in its quest to obtain nuclear weapons and that the strikes were necessary to preempt that outcome.

Iran said the dialogue with the U.S. over Tehran's nuclear programme is "meaningless" after Israel's biggest-ever military strike against its longstanding enemy, but said it is yet to decide on whether to attend planned talks on Sunday.
