The U.S. is considering targeting Iran's uranium enrichment facility at Fordo, five sources familiar with the matter told CBS News.

Since shortly after it was founded in 1948, Israel has been intent on building a nuclear program to ensure its survival.

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.
