Trump’s tweet raising the prospect of nuclear war with North Korea isn’t in violation of Twitter’s guidelines, the company says, and will remain online. In the tweet, Trump boasted that his “Nuclear Button” is “much bigger” and “more powerful” than the one belonging to North Korean leader Kim Jong Un – a combative and childish taunt that raises serious questions about Trump’s fitness for office, as well as to what extent Twitter is complicit in allowing him to publish threats of this nature to its platform.

The tweet today has around 353,000 “Likes” on Twitter – which makes it one of the most-engaged with tweets in recent days, including Trump’s year-end tweet wishing everyone – “even Fake News Media” – a Happy New Year. That tweet had neared 200,000 Likes, while another Fake News-related tweet the day prior had topped 200,000.
