When asked about his vision of US foreign policy, Trump said that he'd make the US military so big and strong that no one would "mess with [the United States]."
"If Russia wants to go into Syria and bomb the hell out of ISIS, I'm sort of ok with that," Trump said during a talk with NBC's anchor Matt Lauer. "If Putin wants to go in and drop bombs on ISIS, I'm ok with it, but we have to do it too."
Trump also added that if he becomes the next US president, he'd have a good relationship with Russian President Vladimir Putin.
"If that happens, I'm sending them back," Trump said.
