Great question: Why does the USA subsidize the defense of Europe while Europeans beat their proverbial swords into Multinational Corporations? Poland alone (or France, England, and Germany) is perfectly capable of defending Western Europe from any perceived Eastern Threat.
Only Trump posted NATO allies to pay their unpaid dues. Europe and other wealthy places should be capable of defending themselves rather than the United States being their uncompensated security force. Doesn’t mean we can’t be the biggest and best just that our blood and treasure shouldn’t be the only sacrifice in conflicts that have little to do with our interests. Trump rebuilt the military and pursued an aggressive strategy of trade relationships. He tried to sell North Korea on western style economic prosperity even creating a mock resort destination video. Engagement was key for Trump. Trump was a wild card but Trump also many times told Europe to avoid getting dependent on Nordstream 2 and Russian energy. He understood it out Europe at a strategic risk. It’s his strategic engagement and advocating allies to react in their self interest that defies the narrative that Trump was Putin’s puppet. His America First along with buy and hire American themes were proven true by Covid and the supply chain disruptions. He upset a lot of allies because he was holding them accountable.
The dollar ax the world’s reserve currency depends strongly on America’s power and influence, and a major part of that influence rests on America guaranteeing global security. Without this, there is no motivation for other countries supporting the Breton Woods agreement that cemented the dominance of the dollar in global trade.
Believe me, you do not want to see the USD collapse, because the demand for the USD has been keeping the US economy afloat for decades in spite of levels of spending other countries could only dream of.
