I do not see any difference between Trump and North Korean president both are psychos who want the world to face another last world war.
Even if North Korea may not match US in technology and arm and weapons but it will have full support of China because North Korean defear will be seen as China's loss.
Nope... Trump is just showing off to improve his approval ratings. Once they are back on track, then he'll announce that he has reached some sort of a deal with the fat boy, and there is no need for any missile attacks.
