Israel's Defense Minister Israel Katz said Thursday that Tel Aviv is prepared to resume its war against Iran and is awaiting approval from the United States, warning Tehran could be pushed "back to the Stone Age" if hostilities restart.

"The IDF is ready both defensively and offensively, and the targets have been marked," Katz said in a video statement.

"We are awaiting a green light from the United States – first and foremost to complete the elimination of the Khamenei dynasty... and additionally to return Iran to the Dark Age and the Stone Age by destroying key energy and electricity facilities and dismantling its national economic infrastructure."

"This time the attack will be different and deadly, delivering devastating blows in the most sensitive places," he said in a statement released by his office.

With the attacks on hold, attention has shifted to the shipping lanes off the coast of Iran.
