What exactly is there in the USA's destruction of the economic norms that have always served it, or in the pointless dumping of its hard-won soft power, alienation of its allies, deliberate weakening of its intelligence gatherers, rampant open corruption from its leadership, or in any other of the innumerable harms it's inflicted on itself the last 18 months, that you think is conducive to the US maintaining its superpower status?
What destruction? US GDP growth has recovered to the pre-COVID trendline while EU lags behind it's already-slow previous pace.
You actually typify the myopia of many of Trump's supporters. "Cash in today: fuck tomorrow."
Even if the US isn't fading, the message is still clear: the country is adopting a more isolationist stance and has no problems alienating its allies. Why would you want to continue to tie yourself to a nation like that?
