More ranting and raving from both sides, but until actual shots are fired, it's just hot air.
Kim knows that shooting down an American bomber would be suicidal. 
Trump, or at least his advisers, know that an attack on North Korea would result in missiles raining destruction on Seoul and Tokyo killing many millions of innocent people and wreaking possibly irreversable havoc on the world economy.  
Hopefully the stalemate continues until adults take over the conversation.
