So, Kyle, I thought you felt the end of American global hegemony was a good thing? I mean, that's what I've gathered from a lot of your posts in the past. But this post suggests you don't think that. Or am I missing something?
As far as America drifting toward isolationism... It definitely is under Trump. Who knows what will/would happen under a future administration. But in terms of its not being able to remain a global power... I think a lot of people (at least people on the left) are aware that at the end of this century, the US will almost definitely not be the first power in the world. On the right, I don't know. Until Trump, I thought the Republican Party's main goals re global dominance were pretty much those outlined in Project for a New American Century. Now, however, their goals mainly seem to be: 1) own the libs; 2) pretend that fossil fuels are "patriotic" and still the future; 3) deny global warming while grabbing as much wealth and power as possible; and 4) keep the rank and file right-leaning voters too occupied with lib-owning, gun-loving, abortion-hating, and bathroom-defending to notice 2 and 3. Not a lot of room in there for higher goals, developing future-looking technologies, soft power, or even thinking about what the US's place of global leadership in the 21st century should or shouldn't be, and how to get there.*
*That said, there's always room to keep selling weapons to anyone who will pay the price, no matter what their goals are as long as their money is green.
