0bama created isis and let it flourish several years, making excuses for them, saying they're not real muslims, etc. Trump began attacking them inmediamente after taking over and less than a year later still intent on wiping them out, he is getting closer to that goal.
NY Times already declared victory
A War Trump Won
There is nothing more characteristic of the Trump era, with its fire hose of misinformation, scandal and hyperbole, than that America and its allies recently managed to win a war that just two years ago consumed headlines and dominated political debate and helped Donald Trump himself get elected president — and somehow nobody seemed to notice.
I mean the war against the Islamic State, whose expansion was the defining foreign policy calamity of Barack Obama’s second term, whose executions of Americans made the U.S.A. look impotent and whose utopian experiment drew volunteers drunk on world-historical ambitions and metaphysical dreams. Its defeat was begun under Obama, and the hardest fighting has been done by Iraqis — but this was an American war too, and we succeeded without massive infusions of ground troops, without accidentally getting into a war with Russia, and without inspiring a huge wave of terrorism in the West.
Why haven’t we noticed this success? One reason is the nature of our victory: As Max Abrahms and John Glaser wrote recently in the Los Angeles Times, the defeat of the Islamic State didn’t happen the way many foreign policy hawks envisioned, because it didn’t require also going to war with Bashar al-Assad or creating a new Syrian opposition army. At the same time, it happened more easily than intervention skeptics feared — so there isn’t a pundit chorus, right or left, ready to claim vindication in the victory.
