Michael Schmidt's new book:
#Trump "cavalierly discussed the idea of using a nuclear weapon against #NorthKorea, saying that if he took such an action, the administration could blame someone else for it to absolve itself of responsibility"
...the prospect of how many people could be killed had "no impact on Trump."
Trump was also "baffled and annoyed" that he would need congressional approval in order to conduct a preemptive strike on North Korea."
