Says Barack Obama “founded ISIS. I would say the co-founder would be crooked Hillary Clinton.”

— Donald Trump on Wednesday, August 10th, 2016 in a speech in Sunrise, Fla.

Donald Trump has found a ferocious way to describe President Barack Obama and Democratic nominee Hillary Clinton: as the founder and co-founder of ISIS, the terrorist group behind beheadings of Americans and lethal attacks around the world.

Speaking to thousands of supporters at a Broward County arena Wednesday, Trump vowed to “knock the hell out of ISIS” before pointing the finger at the Democrats.

“ISIS is honoring President Obama,” he said. “He is the founder of ISIS. He is the founder of ISIS, OK? He is the founder. He founded ISIS. And I would say the co-founder would be crooked Hillary Clinton.”

Trump has been making similar comments for several months, and he repeated his latest talking point in an interview with Republican radio host Hugh Hewitt the day after his Broward speech.

When Hewitt proposed a more cautious interpretation of his assertion — that Obama and Clinton “created the vacuum” in the region and thus “lost the peace” to ISIS — Trump rejected that formulation, sticking with the most literal version of “founder” and “co-founder.”

“No, I meant he’s the founder of ISIS,” Trump told Hewitt. “I do. He was the most valuable player. I give him the most valuable player award. I give her, too, by the way, Hillary Clinton.”

Hewitt pushed back, saying: “But he’s not sympathetic to them. He hates them. He’s trying to kill them.”

Trump dismissed that again, saying: “I don’t care. He was the founder. The way he got out of Iraq was, that, that was the founding of ISIS, OK?”

And hours after the Hewitt interview aired, Trump tripled down on the attack in a speech to the National Association of Homebuilders in Miami Beach, once again accusing them of being the founder and co-founder of ISIS.

Friday morning, however, Trump put out a tweet that said his comments were meant to be sarcasm.

Let us be clear: It is wildly inaccurate to say Obama or Clinton “co-founded” ISIS.

Experts have repeatedly told us that the sources of ISIS are complex and interconnected.

But Trump’s provocative comment glosses over all of that nuance.

For starters, the terrorist group’s roots pre-date Obama’s presidency and Clinton’s role as secretary of state.

ISIS has used several names since 2004, when longtime Sunni extremist Abu Mus‘ab al-Zarqawi established al-Qaida in Iraq (AQI), also known as the Islamic State of Iraq (ISI) and more recently the Islamic State of Iraq and the Levant (ISIL), according to the National Counterterrorism Center.

After he was killed in a 2006 U.S. airstrike, the group became the Islamic State of Iraq. In 2013, the group was referred to as the Islamic State of Iraq and al-Sham and then just the Islamic State in 2014.

The most prominent leader of the group we now call ISIS has been Abu Bakr al-Baghdadi, who became the leader in 2010.

Democrats often blame President George W. Bush for the creation of ISIS because al-Qaida flourished after the overthrow of Saddam Hussein.

But you could also argue Obama’s decision to leave Iraq after 2011 contributed to the security vacuum that gave ISIS the chance to put down roots and regroup.

The Trump campaign sent us links to articles about how the Obama administration handled the situation in the Middle East that influenced the rise of ISIS.

As for Clinton, Trump’s campaign has previously pointed to her vote as a senator to authorize force in Iraq in 2002. While Clinton does bear some responsibility for the Iraq war that gave ISIS an opening, she isn’t solely responsible: The vast majority of senators — from both parties — joined her in supporting the intervention advocated by Bush.

“So yes, Hillary’s vote for President Bush’s misguided policy to build democracy in Iraq directly assisted the Republican decision that opened the door to the radicalization of Iraq and destabilization of the Levant,” Joshua Landis, the director of the Center for Middle East Studies at the University of Oklahoma, told us in July when Trump attacked Clinton. “Bush’s destruction of the Iraq army and state is the single-most important decision that led to the expansion of al-Qaida into the region and later emergence of ISIS.”

Trump’s campaign has also pointed to Clinton’s positions on Syria and Libya as evidence for allowing ISIS to grow. As secretary of state in 2011, she echoed Obama’s support for regime change in Syria and said Syrian President Bashar al-Assad needed to “get out of the way.”

“Clinton’s enthusiasm for regime change in Libya in 2011, which Obama endorsed, resulted in the collapse of order there, which ISIS and others have exploited,” Christopher Preble, a defense expert at the libertarian Cato Institute, previously told PolitiFact. “That is a fair criticism, in my opinion.”

In recent years, the United States has targeted ISIS militarily, with some signs of progress and some setbacks.

As Hewitt suggested in the interview, it’s possible to argue that the administration’s withdrawing from Iraq, its lack of support to anti-Assad rebels in Syria and its decision to intervene in Libya contributed to the power of ISIS.

These concerns track those we’ve heard from foreign-policy experts.

Our ruling

Trump said Obama “founded ISIS. I would say the co-founder would be crooked Hillary Clinton.”

There’s a credible critique that Obama’s and Clinton’s foreign-policy and military decisions helped create a space in which ISIS could operate and expand. But Trump explicitly rejected this formulation, saying he literally means Obama is “the founder of ISIS” and Clinton is the “co-founder.”

In reality, the founder of ISIS was a terrorist. It is run by terrorists. Obama has said destroying ISIS is his “top priority.”

All this makes Trump’s statement a ridiculous characterization. He’s doubled, tripled and quadrupled down on it in various venues and has reinforced that he meant his words to be taken literally.

We rate it Pants on Fire.
