Will the US talk to Iran?

Donald Trump says he was about to strike Iran after the downing of a US drone, then backed off, fearing loss of lives.

The United States called off a military strike on Iran at the last minute.

It's a move that might not sit well with regional allies.

Saudi Arabia, the United Arab Emirates, and Israel want President Donald Trump to keep up its tough stance against Tehran.

But is Trump serious about carrying out an attack against Iran?

Or is he just ramping up pressure?

And is there room for diplomacy?
