I don’t think our method of internal government would matter as much to the world as the foreign policies of the individual leader. For reference on that see 2016-2020.
Likely more introverted and make the world a better place for most but Canada and Mexico might be in trouble. Eg here in Australia you’d hope we kick all the US bases out of Australia, which were a bad fucking idea in the first place.
The externalising of the shit show of inevitable consequence of being a dictatorship might be a neighbiir issue eg instead of just rhetoric about those damn immigrants, invade Mexico to sure up the borders. One hopes the rest of the world would rally behind Mexico, except perhaps like minded “bros” like Russia, Hungary, North korea, Vietnam, Camboida, Myanmar etc etc.
Depends on your demographics a bit. Dictatorships like to scapegoat ethnic minorities or other out groups (see Pinochet’s, Mao’s, Pol Pot’s, etc extermination of scientists and educators) for society’s problems. These groups of people tend to experience much greater intensity of oppression under dictatorships than already present in the US. This tends to change culture on a fundamental level because most people actively try to fit in with the in group to avoid becoming a target themselves.
While present to some degree in our current system, another core characteristic of dictatorships is that self enrichment for those in power is the primary driving factor for decision making. Dictators don’t need to pay lip service to making decisions for the greater good. You see this especially prominently in dictatorships in developing countries with valuable resources… The dictators and their close friends take all of the wealth from resource extraction for themselves and everyone else lives in extreme poverty. Yes we have wealth inequality already, but it would be accelerated even more. You could see even highly skilled professionals having a hard time making ends meet (or in jail for being too smart and having “ideas”), and even more homelessness, potentially even wide scale famine.
In terms of geopolitics… Our relationship with allies would become about how the relationship personally benefits those in power.
Depends on whether the dictatorship is competent or incompetent. Businesses need years of lead time to negotiate deals, build factories, make a profit. But they can’t make plans for the future with a government that is run by idiots. That’s a guaranteed money-loser.
The cons would outweigh the pros.
We would be back to the 2000s where the world was cautiously allied with the U.S during the Bush years. Like, the world depends on the U.S for a lot of things and to lose it’s support, ally and everything to dictatorship would be detrimental. Trump is orchestrating a U.S where he thinks everyone should bow to the country, under his rule. It’s not about making America Great Again, it’s about making Trump Great Again.
