President Donald Trump is touting his administration’s tough approaches to North Korea and Iran.

Trump, speaking at the annual National Rifle Association in Dallas on Friday, says it was his “position of strength” that is bringing Pyongyang to the negotiating table.

He is mocking critics’ concerns that he would start a war with North Korea and instead says “things were going really well.”

Hours earlier, Trump said a date and place for his upcoming summit with North Korean dictator Kim Jong Un would be announced in the coming days.

The president is also repeating his criticism of his predecessor’s negotiations with Iran to halt its nuclear weapons program. Trump will make a decision later this month as to whether the United States will remain in the deal.
