Grass. Trees. Walls. Even deeply buried caves. All gone in a heartbeat.

Virtually nothing but rubble was left after the U.S. Air Force dropped their M.O.A.B bomb on an Islamic State position in Afghanistan earlier this month.

Now, the first pictures and videos are coming out of the region where the so-called “Mother of all Bombs” hit.

The images serve as a striking warning to radical Islamic terrorists around the world: Don’t mess with President Donald Trump and the U.S.A.

So how did this bomb come to be?

The Air Force account, written in March 2008, said MOAB “started out simply as an idea” that became a request in late November 2002 as the administration of George W. Bush was contemplating invading Iraq to topple President Saddam Hussein.

The Air Force conducted and released video footage of the bomb’s final test detonation on March 11, 2003, just days before the U.S. launched its invasion, which successfully removed Saddam from power but led to an unanticipated Sunni Arab insurgency that created a military quagmire and has yet to return Iraq to normalcy.

Asked about the test on the day it was conducted, then-Defense Secretary Donald H. Rumsfeld said, “There is a psychological component to all aspects of warfare. The goal is to not have a war. The goal is to have the pressure be so great that Saddam Hussein cooperates. Short of that, an unwillingness to cooperate, the goal is to have the capabilities of the coalition so clear and so obvious that there is an enormous disincentive for the Iraqi military to fight against the coalition, and there’s an enormous incentive for Saddam Hussein to leave and spare the world a conflict.”

The 2008 Air Force account quoted one of the MOAB project leaders, Robert Hammack, as saying many of the bomb parts were engineered and made in-house, and that the project drew so much interest that experts came out of retirement to work on it. Once built, the bomb was transported to an ammunition depot in Oklahoma to be filled with explosive materials and painted.

“A little known fact is why the MOAB is green,” Hammack was quoted as saying. “Since we were in such a rush to get the weapon into our inventory to send over to aid the (Iraq) war effort, resources were limited. The weekend the MOAB arrived, the only color available in the amount we needed was John Deere green.”
