What about Obama being the "founder of ISIS"?

Yes, Obama Is a Founder of ISIS  . . . "It is a myth, as the White House now claims, that President Obama inherited an Iraqi mess from President Bush and had no choice but to withdraw U.S. troops in the absence of a status of forces agreement. The problem was not that Iraq and Prime Minister Noor al-Maliki wanted the U.S. to leave, but that the force Obama wanted to leave was just too small. As Patrick Brennan has written inNational Review:
. . . 

"So unserious was Obama’s attempt to “degrade and destroy” ISIS that he at one point spared ISIS oil facilities, a prime source of its funding, because attacking them might hurt the environment.

"If you wondered why our air campaign against ISIS was inept, consider the statement by Mike Morell, speaking on the “Charlie Rose” program That we didn’t take out the oil facilities that ISIS was using to become the best financed terrorist organization in history because of our concern the environment would be harmed. As the Washington Times reported:" . . .

Intended as sarcasm or not, Donald Trump is right on this one. President Obama deserves credit as a co-founder of ISIS.

Andrew C. McCarthy: Obama’s Iraq Policy Did Not Create ISIS  . . . "Our challenge in the Middle East is that sharia supremacism fills all vacuums. It was this ideology that created ISIS long before President Obama came along. And if ISIS were to disappear tomorrow, sharia supremacism would still be our challenge. It is critical to be an effective political opposition to the Obama Left. But being effective means not letting the political part warp our judgment, especially where national security is concerned."

Fact Check: Were Obama and Hillary Founders of ISIS? You Bet

. . . "Obama’s disastrous withdrawal of U.S. combat forces from Iraq in December 2011 clearly enhanced the ability of AQI and ISI to seize control of large portions of Iraqi territory and certainly contributed to the birth of ISIS. It also opened the door for Iran to fill the vacuum.

"But as the August 2012 defense intelligence report states, that was the plan all along. Obama and Hillary wanted to create an ISIS-controlled enclave in Syria, “in order to isolate the Syrian regime, which is considered the strategic depth of the Shia expansion (Iraq and Iran).' ”
