Every month since then, he has repeated the claim, simply updating the number of months. For instance, on Sept. 7, he said, “We have done better in eight months of my presidency than the previous eight years against ISIS.” (Never mind that the Islamic State terror group emerged as a significant force in Iraq and Syria in 2013, when it captured and raised its flag over Fallujah.)

Now, in the wake of the terror group’s loss of its de facto capital of Raqqa, Syria, the president is taking yet another victory lap. But it raises the question: Has the Trump administration done more in its short term in office than the administration of Barack Obama?

The Facts

The Islamic State can ultimately be traced back to a group called al-Qaeda in Iraq, which was started by a Jordanian terrorist named Abu Musab al-Zarqawi, and arose in response to the U.S. invasion of Iraq in 2003. (Trump supported the invasion of Iraq, though he falsely denies that now.)

Eventually, al-Qaeda in Iraq had more or less petered out, but the civil war in Syria that started in 2011 breathed new life into what had become a moribund organization, since it led to a vacuum of governance in the country. The Islamic State then moved into Iraq, in part because of Obama’s decision to withdraw troops in 2011. (Trump had urged a rapid withdrawal at the time but he ignores that now when he criticizes Obama for this decision.) Then-Defense Secretary Leon Panetta, in his 2014 memoir “Worthy Fights,” said that he warned Obama that without U.S. troops in place, Iraq “could become a new haven for terrorists.”

Another factor in the rise of the Islamic State was the rampant mismanagement by the government of Prime Minister Nouri al-Maliki, which greatly degraded the Iraqi military and exacerbated tensions between Sunnis and Shiites.

The Islamic State reached its height of control in late 2014, with defense consultant IHS Jane’s estimating a reach of 35,000 square miles in January 2015. On Sept. 10, 2014, Obama announced the formation of an international coalition to defeat the Islamic State, and a month later the Defense Department formally established Combined Joint Task Force — Operation Inherent Resolve, which coordinates the activities of 73 nations in the mission. (Most of them do not contribute to warfighting but are expected to help with stabilization efforts in cleared areas.)

U.S. defense advisers then had to train and arm Iraqi security forces from the ground up. After three years, their performance has improved considerably, experts said.

By the time Trump took office, Islamic State territory had fallen to 23,000 square miles, according to Jane’s. As of June of this year, the Islamic State controlled 14,000 square miles — and it has fallen further since. But far more of the “liberation” of territory, in square miles, took place before Trump took office, including the recapture of east Mosul as well as cities across Anbar province (Fallujah) and key Syrian cities such as Manbij that controlled the Turkish-Syrian frontier.

This map, from the website of the coalition, shows how much ISIS territory had fallen by the time Trump took office:

This map shows the difference in the first six months of the Trump administration.

Indeed, the plan that resulted in the liberation of Mosul and Raqqa was launched under Obama, and there wasn’t much change other than looser rules of engagement with regard to striking targets of opportunity, resulting in an increased tempo. The assault on Raqqa began in November — two months before Trump took office, using the same coalition that ultimately captured the city.

“There is no doubt that the Trump administration followed the basic strategy set in place by the Obama administration,” said Michael Morell, former deputy director of the CIA. “There is no doubt that Obama would have gotten where Trump is at this moment as well.”

“There were no significant changes in the overall plan in combating ISIS,” said Ali Soufan, chief executive of the Soufan Group, and a former FBI agent who specialized in international terrorism cases. “What we are witnessing today is mostly the fruits of what the former administration started.”

Morell added that there is a “compelling argument” that some tactical changes made by Defense Secretary Jim Mattis, such as more Special Forces on the ground and putting them closer to the fight, resulted in an acceleration of the coalition meeting its objectives. Trump also allowed commanders on the ground to make some battlefield decisions, avoiding micromanagement from Washington. (One example often cited by officials is when Syrian Democratic Forces requested the use of V-22 Osprey aircraft to cross Lake Assad in order to surprise militants in the town of Tabqa, which was approved on spot without getting buy-in from the White House.)

Another tactical shift was a “campaign of annihilation” — surrounding cities held by militants — that has ensured that no militants will escape from cities. Obama’s defense secretary, Ash Carter, had left an escape route for militants to minimize destruction to cities and deaths of civilians.

Human rights groups have protested the change in tactics, saying more civilians have been killed under Trump than under Obama. Statistics from U.S. Central Command suggest that the number of civilians killed has more than tripled under Trump, from 199 between 2014 and 2016 to 786 as of Oct. 26, with 519 more cases still under investigation.

Anthony Cordesman of the Center for Strategic and International Studies dismissed land as a fairly useless metric given most of the territory is desert. But he said other metrics, such as air power, also bolstered the case that Obama had done more.

According to Cordesman’s calculations, coalition forces have flown 63,758 sorties, of which 23 percent were flown under Trump. As for air munitions used, coalition forces dropped 65,731 in 2014-2016 versus 36,351 in 2017. That amounts to 36 percent under Trump.

“Obama set up virtually all the structure that did the key fighting under Trump,” Cordesman said. He attributed Trump’s claims of dramatic success as akin to “saying nothing happened in Europe until the allies in the West crossed the Rhine and entered Germany on March 7, 1945.”

“Obama fashioned the strategy, the alliances and assembled the forces to destroy the caliphate, but the culmination of the process has occurred on Trump’s watch,” said Bruce Reidel, a senior fellow at the Brookings Institution. “It’s a good example of Trump keeping Obama policy basically intact, not dramatically altering it. Now the territorial battle is coming to a close and the much harder ideological conflict is still to be won; that is Trump’s challenge.”

We asked the White House for backup of the president’s statement. Officials blamed Obama for allowing the rise of the Islamic State and said a fuller response would be forthcoming, but we did not receive it before publication. Update: A White House official said the president was referring to the rate of liberation under his watch, both in terms of people and land. From Sept. 2014 through Jan. 2017, land was liberated at a rate of 1,071 miles a month, versus 2,330 a month under Trump, he said.

The Pinocchio Test

A president taking credit for a successful outcome started by his predecessor is a time-honored tradition. Obama certainly claimed repeatedly that he saved General Motors during the Great Recession, even though he built on steps first taken by George W. Bush.

That still does not make it right. Trump exacerbates the braggadocio by specifically saying he has done “by far” more than Obama, even though he inherited a structure and plan developed by Obama. Experts credit Trump with some tactical shifts that may have stepped up the tempo — though the number of civilian deaths has soared as a result. But in reality, according to several metrics, more was done under Obama.
