Let’s say Trump wins and Europe loses its security guarantee from the US.
Then the EU beefs up its military and coordinate its combined forces and military production up to the point that they are no longer in need of US military assistance in future conflicts.
What will be the ramifications for the US if this was to play out in terms of trade, geo political influence etc.
It’ll certainly mean a huge loss if power and influence for the US. Right now the Europeans pretty much follow the US’s lead when it comes to trade deals, political and military alliances etc. And they turn a blind eye to US imperialism in the Middle East and Latin America. All this would change and once the Europeans become more aware of their own power and willing to use it, they’ll be a real geopolitical rival to the US.
