President Donald Trump issued a bizarre threat against Iran -- triggering confusion and alarm.

Congress curtailed the president's war powers in February after he escalated tensions the month before with Iran, which like the United States is now grappling with the coronavirus pandemic.

Trump reignited tensions with a tweet Wednesday warning that "Iran or its proxies" were planning a "sneak attack" on U.S. troops or assets in Iraq, which Teheran had done in January in response to the drone strike killing of general Qasem Soleimani.

Other social media users were perplexed by the threat, which appeared to use language from confidential briefings -- like the intelligence briefing Trump had scheduled about an hour before his tweet was posted.
