BRUSSELS (AP) — U.S. President Donald Trump is forecasting an unspecified "escalation" between the U.S. and Iran.

Trump also says Iran is treating the U.S. with more respect, though there is no evidence to support Trump's claim.

Trump withdrew the U.S from the Iran nuclear deal earlier this year, reinstating economic sanctions that had been lifted under a deal among Iran, the U.S. and other world powers in exchange for curbs on Iran's nuclear program.

Trump was asked about Iran at a news conference in Brussels, where he wrapped up his participation in a NATO summit.

He says Iran is feeling a lot of pain as a result and that at some point Iran will "call me and they're going to say let's make a deal, and we'll make a deal."
