Trump's salute is nothing, what is worse is how Trump showers Kim Jong-un with praise in front of every reporter he has talked to since. Let that sink in, Trump showered a man with praise that has tortured to death American citizens, thrown American citizens into labor camps just to use them as diplomatic pawns, starved his own people, runs the most repressive regime in the history of civilization (Stalin's Russia was a beacon of freedom compared to North Korea today), and has hundreds of thousands of his own citizens locked up in concentration camps so large they are visible from space.
It would be like FDR meeting with Hitler in the late 30s, calling him a talented man, who loved his people and was loved by his people, and just gushing with praise for him in front of the reporters, all the while knowing about his death camps, and doing so in exchange for nothing but the same empty promises he was giving everyone else.
As I have said before on here, this all goes to show you how spineless the Democrats are. If Trump had a D after his name, every elected Republican in the country would be in front of every camera in the country talking about Trump is showering a man with praise that has tortured Americans and runs the most evil regime on earth. They would be calling him morally and intellectually unfit for office, and demanding his resignation, yet the spineless Democrats can't even make an issue out of it.
