In the last GOP debate, frontrunner Donald Trump called the Bush administration's decision to invade Iraq a "big fat mistake" that "destabilized the Middle East."
"The war in Iraq, we spent $2 trillion, thousands of lives. We don’t even have it. ... Obviously, it was a mistake," Trump said on the debate stage.
The Kelly File asked Iraq War veterans Pete Hegseth and Carl Higbie to weigh in.
Higbie, a former Navy SEAL, said the wisdom of invading Iraq is up for debate, but that he's supporting Trump because of the billionaire's abilities to accomplish goals.
"Was it a mistake to go in Iraq? We can armchair quarterback all we want. But the fact of the matter is Donald Trump will set systematic goals to disassemble ISIS, to destroy them and take them off the face of the Earth," he said.
Higbie said that under Trump, ISIS could be destroyed in two years.
Meanwhile, Hegseth said that Trump's comments "trashing" the Iraq War were an insult to the military members who served there.
Hegseth, a decorated Army National Guard veteran, accused Trump of "using talking points from MoveOn.Org, Nancy Pelosi and Harry Reid...when you and I both know, having served there, that in the Iraq surge we turned that war around, won the war, handed it to Barack Obama and he failed and left it to fall to ISIS."
He said that "every veteran should be offended" by Trump saying that the war was a mistake and that 9/11 happened because of George W. Bush (Trump later clarified his remarks, saying he's "not blaming anybody" for 9/11).
