Trump blasted for tweeting USA flag — with no words — as world worries he may have started war with Iran

State TV in Iraq reports Iranian Gen. Qasem Suleimani was killed at the Baghdad airport.

Suleimani is a revered figure in Iran and analysts worry Iran will be forced to escalate tensions with their expected response.

Trump took to Twitter following the reports.

He did not claim credit for the assassination -- or try to downplay tensions and calm nevers.

Instead, he just tweeted a picture of an American flag.

Former Ambassador Michael McFaul was less-than-impressed with Trump's communications.

"At this moment, I would like a little more specificity about our strategy from our commander in chief than this," McFaul tweeted.
