> This guy does not have a history of bumbling around. He seems to be quite an effective man of action. I took the "best case" to mean that Trump is so caught up in his daily Twitter fueds (Arnold Schwarzenegger today) to push any significant legislative changes or start a war. Clearly Trump has had some degree of success in the business and marketing world. Personally I think Trump knows exactly what he is doing when he makes outrageous public statements or goes after someone (distracting from issues like Russia, his conflicts of interest, the repeal of the ACA etc), but it's not a great leap to see how that behavior could cause issues in the world of international diplomacy. He has already made comments about nuclear proliferation, nuclear arms races, the one China policy, and the role of Russia in our recent election cycle. The linked article alludes to how quickly normality can spiral out of control especially if everyone assumes "it can't happen".
