You're saying you're more divided, what has Trump ever done to cause or further this?
Also when you say his love for Kim Jong Un, the term "rocket man" comes to mind, I cannot comment on the Putin situation as I'm not really educated on that topic.
Lets list out your enemies: North Korea, Russia, China and Iran
For starters he waged a trade war on China, my knowledge is weak on the rest, but as far as I don't see him getting bed with any of your enemies.
Damage to your constitution? What about everyone else who tries to push their politically correct agenda on the rest of the population against their freedom of speech (i.e. people self defining genders and forcing that on other people to call them that) - or go after peoples guns? which I also believe are protected by your constitution.
North Korea and Russia are no friends of the USA, and you cannot blame Trump for "allowing" them, its not like they need his permission and say so to do what they do, they do it anyway.
Feel free to correct me if I get something wrong, because I prefer the truth over opinion.
