A photo of Jordan's King Abdullah quickly went viral, showing him in a military uniform after vowing to attack ISIS to avenge the brutal execution of a captured Jordanian pilot.

Abdullah reportedly mentioned Clint Eastwood's character in "Unforgiven" when he met with U.S. lawmakers this week about his planned response to the ISIS brutality. 

The symbolic file photo was posted on Abdullah's Facebook page. It's unclear when it was taken and officials emphasized he won't be taking part in any operations against ISIS. 

Jordanian fighter jets began striking ISIS Thursday near Raqqa, Syria. Reports indicated 55 ISIS fighters were killed, including a commander known as the “Prince of Nineveh.”

Rep. Duncan Hunter (R-Calif.) weighed in this morning on "America's Newsroom," contrasting President Obama's response to King Abdullah's.

"This president does not have any red lines that if crossed, the president will say 'we're gonna go after them.' ... King Abdullah sounded like President Bush post-9/11 when the president said we're going to hunt you down to the ends of the earth and we're going to come after you. It was righteous anger and it was totally warranted," said Hunter.

Hunter, who met with Abdullah two days ago, said the Jordanian military needs Hellfire missiles, ammunition and fuel in order to sustain a campaign against ISIS.

Hunter said some contingent of U.S. ground forces should be on the ground to help a larger Jordanian force and call in airstrikes.
