With President Trump going after North Korea, there's one man who says he can HELP the situation ... Dennis Rodman!

Of course, The Worm has not only met with Kim Jong-un ... but he worked for Trump on 'Celebrity Apprentice.'

He's got his hand in music now too, Rodman's featured on Mansionz new single -- which hit the top of Spotify -- called "Dennis Rodman" ... of course.

He's the perfect middleman, right?

Rodman says he hasn't spoken with Trump about his experience in Pyongyang ... but would love to brief POTUS if he can find the time.

Couldn't hurt, could it?
