The Obama administration’s strategy, albeit slower than a traditional ground campaign, presents a suitable alternative to the traditional large-scale military operations of the past. Eliminating the substantial military requirements in the Middle East provides the U.S. administration with the opportunity to exercise fiscal reforms, strengthening the American economy.
A reengagement in Iraq would undoubtedly have cost American lives and billions of dollars that would have further strained America’s economy and fed into ISIS’ propaganda and recruiting strategies, which would have fueled further resentment against the west and continued the traditional cycle of violence in the region.

President Donald Trump's plan to defeat ISIS is essentially the same as his predecessor, President Barack Obama, despite Trump's frequent criticism of the former president's efforts against the terror group.
The president has so far missed two deadlines he set himself for detailing a new ISIS strategy, according to CNN. That delay, according to the Daily Beast, is because the Trump White House has been asking defense officials to pitch new ideas that could differentiate the current strategy from Obama's.
The strategy put in place by the Obama administration, however, seems to be working quite well, McAslan said. Though the overall strategy hasn't changed, McAslan said, what has "changed is the fact that in 2014, ISIS was at the gates of Baghdad, and now they are a desperate enemy about to be defeated in Iraq’s second largest city."
"The strategy hasn’t changed at all throughout," he added, mentioning coalition efforts to train indigenous forces, advise them, and offer precision air strikes, intelligence, and surveillance.
Iraqi security forces have only about 3% left to go before Mosul is fully liberated from ISIS forces. Once Iraq's second-largest city is recaptured, they will move on to other small pockets of terrain still held by ISIS in Iraq, which include cities such as Hawija, Tal Afar, and Al Qaim.
Meanwhile, coalition-backed Syrian Democratic Forces have continued to push further into Raqqa, Syria, the self-proclaimed capital of the Islamic State. The coalition estimates there are approximately 3,000 to 4,000 fighters left to defend that city.
