"The full strength and might of the U.S. Armed Forces will come down on you at levels never seen before," Trump warned.

The two powers have been exchanging barrages since Israel attacked Iran and killed many of the country’s top military leaders and scientists.

President Donald Trump said the United will come down on Iran “at levels never seen before” if the Middle Eastern country attacks.

New targets appear to indicate an expansion of Israel’s war aims beyond the Iranian nuclear facilities that consumed the first days of the conflict.

The markets have mostly shrugged off Russia's invasion of Ukraine and the Israel-Hamas war. But Israel's conflict with Iran is still in its early days.

Discussing the conflict between Israel and Iran, the former vice president said Trump "ought to be looking elsewhere than Vladimir Putin for advice."

Oil prices climbed on Monday, extending Friday's rally, as renewed strikes by Israel and Iran over the weekend increased concerns that the battle could widen across the region and significantly disrupt oil exports from the Middle East.
