"The United States must greatly strengthen and expand its nuclear capability until such time as the world comes to its senses regarding nukes," Trump wrote on the social media platform.
Trump's proclamation came just one day after he met with top Pentagon officials, including the Air Force deputy chief of staff for strategic deterrence and nuclear integration, a post that broadly oversees the Air Force's nuclear weapons capabilities.
He tweeted after the Wednesday meeting that he was very impressed with the individuals he met:
I met some really great Air Force GENERALS and Navy ADMIRALS today, talking about airplane capability and pricing. Very impressive people!

Earlier this year, the Obama administration proposed a $348 billion plan to upgrade the US nuclear arsenal over the next ten years to improve the missiles and warheads, and improve delivery systems aboard submarines and aircraft.
Trump's tweet wasn't the first time he's promoted expanding nuclear weapons broadly.
During the 2016 presidential campaign, Trump said he could support countries like Japan and South Korea developing their own nuclear weapons, a move that many experts argued could create a strategic arms race in Asia and the Middle East.
