On Tuesday night, President Donald Trump made headlines through his use of the social media platform Twitter once again, this time, by comparing the size of his *ahem* nuclear button to that of North Korean Supreme Leader Kim Jong Un.

The tweet received a mixed response from supporters and critics alike, with some applauding the American president’s refreshing take on geopolitics, and others comparing him to the embarrassing uncle that doesn’t know when to stop talking at Thanksgiving dinner.

The tweet, of course, was in response to an earlier provocation from Kim Jong Un himself, who in a New Year’s Day address extended an olive branch to American ally South Korea, while “reminding” the United States that Kim’s “nuclear button” remains on his desk, ready to order a launch of troubled intercontinental ballistic missile platforms that have yet to demonstrate a survival reentry vehicle.

With all the discussion and debate regarding Kim and Trump’s professional wrestling-style dialogue, one could be forgiven for thinking these two leaders really do have a button on their desks that could order a launch of their nation’s nuclear assets. Could President Trump accidentally set his coffee cup down in the wrong spot and inadvertently start a nuclear war? No. There is no button.

We’re unable to confirm what sort of launch apparatus Kim employs, but you can be nearly certain that he doesn’t have one either. Launching a nuclear weapon is just too complex a process, too labor intensive, with too many people involved to be as simple as that. In reality, deciding to launch a nuclear strike has very little to do with what the president (or Supreme Leader) do physically – because like any other military action – it involves giving the order. Once the order is given, a cascade of procedures executed by enlisted and commissioned personnel are set in motion, beginning with command authorization, and ending with nuclear devastation.
