During his 80-plus days in office, President Trump has modified his positions on NATO, China, Russia and Syria, leading some in the media to accuse him of flip-flopping.

Dr. Sebastian Gorka, however, disagrees.

"In just 84 days, President Trump has replaced divisiveness with decisiveness," Gorka, deputy assistant to Trump, said on "The O'Reilly Factor" tonight. "We have changed the geopolitical reality in the world in just a matter of weeks."

Gorka explained that Trump changed his rhetoric on NATO being "obsolete" and China being an "enemy" to the U.S. because he's a master deal-maker, and he will do what's in the best interest of the American people.

"I think China understands you can't undermine and subvert America the way you could in last eight years," Gorka said.

He added that the U.S. doesn't have to be "best buddies" with China to ensure that our nation isn't being exploited.

As for today's military strike on ISIS tunnels in Afghanistan, Gorka said that Trump isn't adopting a new, interventionist foreign policy, but instead following through on his campaign promise to obliterate the vicious terror group.

He added that last week's airstrikes on a Syrian air base - which came after Syrian President Bashar al-Assad used chemical weapons on civilians - aren't a flip-flop, but simply Trump showing that he will not tolerate war crimes, as President Obama did with his infamous "red line."

Gorka said that both military strikes send a strong message to other U.S. adversaries, such as Iran and North Korea.

"President Trump is a patriot and a pragmatist at the same time. And that's why you're seeing the decisiveness you're seeing today."
