President Trump told reporters on Thursday of his desire to rid the planet of nuclear weapons, even as his rhetoric against North Korean aggression intensifies.

"I would like to de-nuke the world," Trump following a security briefing in at his golf resort in Bedminster, N.J., according to a press pool report.

North Korea is working on developing intercontinental ballistic missiles, and tested two of them last month. This week it was reported that the country has created a miniature nuclear weapon that can fit inside its missiles.

After the United Nations Security Council unanimously voted to impose new sanctions on Pyongyang over the weekend, North Korea began to escalate its rhetoric, which prompted Trump to threaten "fire and fury" should North Korean aggression continues.

He said earlier in the day Thursday that his "fire and fury" threat against North Korea earlier in the week possibly "wasn't tough enough."

Even as Trump declared he wants to "de-nuke" the world, he added, "Until such time as they do, we will be the most powerful nuclear nation in the world, by far." Trump also mentioned Thursday afternoon that he will push for more funding to go towards anti-missile defense due to the threat of North Korea and other countries.

Ridding the world of nuclear weapons is a task in which the U.S. would need to lead by example. The U.S. currently has 6,800 warheads, according to data from the Federation of American Scientists. Nearly 3,000 are retired, while 4,000 are stockpiled and 1,800 are deployed. Russia, meanwhile, has 7,000 warheads in their inventory.

The United Nations has developed a treaty to ban nuclear weapons, which has been criticized by some countries, including the U.S. as being unrealistic.
