America does influence the world. Over the past 30 years America influenced the world and made it dependent on a lopsided situation where America covered the tab for war and peace. Trump is more about a Dutch Treat approach. This will take some time to get used to. BUT in the end, a date has more control if she covers her own tab.
Paying the world tab, under Obama, for military, trade and human tragedy, became a way for middlemen in America and foreign counties, to scam and skim via the pretense of a giveaway. For example, giving Iran $billions in cash was way to money launder tax payer money under the guise of promoting world peace. Who deals in cash, nowadays, except the black market who wishes to hide its illegal activities. What percent did Kerry and Obama get and where is their golden parachute hidden now? Did Trump, by voiding the deal, cause Obama and Kerry to lose the golden parachute finder fee?
Trump is dealing with the black market global corruption by pulling the plug on the various international wash machines. Global warming was supposed to be an industrial size wash machine for international money laundering. The US was almost committed to $trillions in giveaways for climate related money laundering. Trump sent that wash machine back for a refund. Foreign leaders are upset since they were already picking out the curtains for their retirement homes. They use their own versions of fake news in the hopes of getting the scam back on track.
Why should the US pay for the United Nations only to have third world dictators lecture them on human rights? That rebellion was led by the leftist and used as a tool to shake down America. America is always guilty and has to pay. The world had become ungrateful guests who think it is up to the host to accommodate them. Trump owes hotels and knows how to deal with unruly guests in a polite way. You cover their tab for their stay, up to then, and ask them to leave. While middlemen use this guilt game as a pretense to skim and scam; swamp. The international left is besides itself, since these scams took decades to perfect and only years to undermine.
