Know this: even as the cowardly 29-year-old butcher responsible for the Manhattan attack receives the best medical care on the face of the Earth in the emergency room, the man in the White House is crushing his comrades and his twisted cause from the Situation Room.

There is no one better suited to destroy radical Islamic terror than Donald Trump — and the bad guys are finding that out.

Overseas, President Trump adjusted the rules of engagement so that the commanders in the field would enjoy more day-to-day discretion, rather than have maneuvers dictated by high-minded beltway bureaucrats.

President Obama was tepid, and lectured nervously about war against Islamic terror, always careful to painstakingly tamp out what he feared were the fiery and dangerous emotions of the American people.

Now the gloves are off. And 2017 has been a brutal year for ISIS, their caliphate all but torn away along with their mission for global relevance. In bolstering our forces in Afghanistan, President Trump made it clear that timelines for withdrawal were no longer in effect and the U.S. would keep the pressure on the Taliban and al-Qaeda.

He promised to “Bomb the sh-t out of ISIS,” and in Afghanistan he did just that. When American Special Forces were unable to advance over a tunnel system in an area that had been mined, a MOAB (Massive Ordnance Air Blast) — the largest non-nuclear ordnance we have — was dropped right on top of it.

Stateside, we face an enemy who has learned to adapt, as we saw yesterday. The suspected terrorist, Sayfullo Saipov, arrived here a few years ago from Uzbekistan. He may have had a recent radicalization and embarked on the attack too quickly for law enforcement to have noticed him. It’s called “flash to bang,” a reference to the time between a lightning strike and the crack of thunder that follows.

It is indeed an uphill battle. Which is why we are lucky to have a president who believes in “extreme vetting.”

It’s only common sense that certain immigrants and refugees receive extra scrutiny if they are coming from hotbeds of radical extremism. It is not only a responsibility of the U.S., but the responsibility of its citizens, regardless of the progressive dictates of activist courts, liberal political quislings and straight-up Trump haters.

Last May, President Trump’s speech to the Arab Islamic American Summit in Saudi Arabia was noticeably void of any apologies for the failures of the West.

He was all business, declaring, “This summit will mark the beginning of the end for those who practice terror and spread its vile creed. … But this future can only be achieved through defeating terrorism and the ideology that drives it.”

Say what you will. The terrorist threat has never been more threatened than now.
