Of course, Trump submitted all the Russian proof on North Korea to USA intelligence for forensics and assessment to complete the reason why he believes Putin that North Korea has no long range missiles. No? That is because Trump is afraid of Putin. Trump remembers Putin stating during the election for president if Hillary Clinton is elected there will be nuclear war with the USA. Trump is afraid of Russian Novichok. He is submissive to Putin because it is easier than standing up to him.
After all Putin won Trump a real seat of power. Why not believe him?
Does Trump believe Putin is killing people in Ukraine? Does Trump believe Putin broke a long standing international treaty to invade Crimea and Ukraine? Does Trump believe Russia is directly responsible for the war at the Russian border with Ukraine? Does Trump believe Russians were responsible for the downing of a commercial airliner killing hundreds of people? If not, what is all that Fake News? Is that what Trump believes of USA intelligence? Is USA intelligence Fake News?
There are millions of Americans living in NATO countries; Trump should not take their security so lightly.
