Kim Jong Un threats prompt Trump nuke 'button' tweet

WASHINGTON (AP) – President Donald Trump is boasting that he has a bigger and more powerful "nuclear button" than North Korean leader Kim Jong Un does.

The president's Tuesday evening tweet came in response to Kim's New Year's address, in which he repeated fiery nuclear threats against the United States and said he had a "nuclear button" on his office desk.

Trump mocked that assertion, writing, "Will someone from his depleted and food starved regime please inform him that I too have a Nuclear Button, but it is a much bigger & more powerful one than his, and my Button works!"

Trump doesn't actually have a physical nuclear button.

The process for launching a nuclear strike is secret and complex and involves the use of a nuclear "football" carried by military officers.

Earlier, Trump sounded open to the possibility of an inter-Korean dialogue after North Korean leader Kim Jong Un made a rare overture toward South Korea in a New Year's address.

But U.S. officials are also voicing skepticism about Kim's intentions and repeating the demand that the North give up its nukes.

Using his derisive nickname for Kim, Trump says: "Rocket man now wants to talk to South Korea for first time. Perhaps that is good news, perhaps not - we will see!"
