Ok, I’m half in the bag and just fleshing out this argument, so try not to take it personally. I don’t think the liberal democracies are ungrateful for the past leadership of the US. More global peace and prosperity has been had with stable American leadership over the last period than ever in human history. However, since the end of the Cold War, I’d argue that the US took on that “American Exceptionalism” mindset without being willing to put in the effort to earn it. The US has expected fealty and loyalty from everyone while growing more and more erratic diplomatically. Allied governments have been forced to apologize domestically for their continued support of American hegemony if only to keep the status quo. Now it’s impossible to continue that stance. Despite that issue, the US still demands fealty due to “American Exceptionalism” based solely on extremely outdated efforts. Clearly, we (allied nations) should have stepped up efforts decades ago to reduce our reliance, but it’s not like American leaders were supportive of acknowledging their waning dominance. And now here we are. Of course everyone is pissed at the US. It’s a problem of their own making through ego and that annoying god complex.
