Israel's military says the nine nuclear scientists killed played spent decades working on Iran's nuclear program.

President Trump said it was a "good conversation" but noted the Russian leader had vowed "very strongly" during the call to respond to Ukraine's Sunday drone strikes on air bases in Russia.

The deal provided Iran sanctions relief for limits on its nuclear program. But now there's new Iranian leadership and more uranium in their stockpile than when Trump abandoned the agreement.

Before the U.S. pulled out, the deal gave Iran money and gave the world assurances that Iran wasn't trying to build nuclear weapons.
