First, maybe look at what is happening on a local level, where people actually care about what is happening. People want a good job, they don't actually give a fuck about what someone half a world away thinks of them. Trump has brought in jobs, that is indisputable. He has also gotten more POW and various other hostages home that no one cared to rescue. He has created laws that allow good behavior in prison, to be released from jail earlier. As well as lighter punishments for first time offenders. He has brought more women into government than ever before. He has made America more energy independent, which makes USA have more leverage in affairs dealing with places like Saudi Arabia. He has pulled out of rediculous trade deals that screwed over our production industry, and stopped giving money to places like Iran. He has brought national focus on the opiod crisis. The list goes on.
Global leverage? USA has the most leverage, regardless of how much they hate USA. It always boils down to "work with USA, or get fucked". No one has the power to say no, unless they team up with China. NATO is another big thing, as stated before in this thread. If USA is the backbone of defense for the entire European. They really can't afford to piss off USA, or they will be exposed. People talk big shit in politics, but only because it has been peaceful for ages. No one has any balls to go HAM, except for Trump. And everyone knows it.
