U.N. ambassador Mike Waltz says pause in strikes against Iran is 'giving diplomacy some space'

Mike Waltz, the U.S. ambassador to the United Nations, said in an interview on 'Face the Nation with Margaret Brennan,' the pause in strikes against Iran is 'giving diplomacy some space' and 'a little bit of time' to work.

He said of President Trump, 'He is a president of peace. He is giving diplomacy a chance.' But he added that 'additional military assets are moving into the region.'

The U.S. paused strikes against Iran Friday and Saturday night after 13 straight days of bombing following the collapse in early July of a nearly three-month ceasefire. On Sunday, Tehran also paused its strikes. Over the last two days, Iranian officials and their Omani counterparts have been having discussions that have been constructive, one Iranian official told CBS News on Sunday. Waltz praised Oman's efforts during his conversation with Brennan.

CBS News reported last week that the rapid pace at which the U.S. is expending some of its most advanced air-defense interceptors and precision-guided weapons in the Middle East is a point of great tension inside the Trump administration.

Senators Bernie Sanders and John Kennedy differ on what the U.S. should be doing in Iran. Sanders, a Vermont independent who caucuses with Democrats and has opposed the Iran war from the outset, told Brennan on 'Face the Nation' that it's time for the U.S. to resume diplomacy with Iran. 'Let's sit down. Let's negotiate with them. Let's stop the killing,' he said.
