Donald Trump Fires Off Childish Response to Kim Jong-un's Nuclear Threat

Donald Trump is firing back at Kim Jong-un's "nuclear button" threat -- but he did it in the most childish way possible.

POTUS hopped on Twitter to let the North Korean leader know "I too have a Nuclear Button, but it is a much bigger & more powerful one than his."

Translation: Na-na na-na boo boo. From the White House, no less.

Trump was responding to Kim's New Year's statement warning he has ICBMs capable of reaching U.S. soil. 

The Prez topped off his powerfully juvenile tweet with ... "and my Button works!"

Kids say the darndest things.
