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.

Israel says it first bombed Iran to stop it from being able to produce nuclear weapons and the “existential threat” they would represent.

Israel escalated its bombings across Iran on Monday, striking Iran’s elite military force and the nation’s state broadcaster and sending thousands fleeing from Tehran, as its offensive entered its fourth day and showed no signs of slowing.
