Former Vice President Mike Pence said on “State of the Union” Sunday that if Israel’s attack doesn’t somehow convince Iran to make major concessions in Trump’s diplomatic attempt to end its nuclear program, then the United States should be prepared to join the conflict.

President Trump has called on Iran and Israel "to make a deal" that ends the war between the two countries. Why it matters: The Trump administration has so far distanced itself from Israel's operation and argued that it would be illegitimate for Iran to retaliate by striking U.

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