President Donald Trump is considering inviting North Korea's Kim Jong-un — who is, it should be remembered, a murderous dictator — to a second meeting at his Florida resort Mar-a-Lago if the upcoming summit in Singapore goes well, according to a new report from Bloomberg.

But, in testament to the president's volatile temperament, Trump is also prepared to walk out of the summit room in the first few minutes if it's not progressing to his liking, the report said.

Trump's goal in the summit is reportedly to get Kim to agree to a nuclear disarmament schedule, according to the article, and he has been advised not to give up any concessions. Only after the North Korean regime has showed it's undertaken "verifiable and irreversible steps to denuclearization" will sanctions relief being.

It's not clear if this relatively defiant stance represents much progress from the war of words that initially prompted Trump to cancel the Singapore summit.

The Bloomberg report also notes that Kim is fearful that the summit might be the site of assassination attempts.
