I think there are physical limits on US power, and we're seeing these limits being reached now. US is simply incapable of producing weapons and ammunition at the rate they're being used in Ukraine. US has now run through much of the existing stocks, and it's operating on very thin margins. I'm sure US will continue to try milk Europe, but NATO isn't strictly necessary for that. Without NATO, Europe is still largely dependent on US, but there won't be a commitment from US. You can think of it the same way NATO is using Ukraine right now, where they provide support, but won't engage Russia directly on Ukraine's behalf. Europe will find itself in the same position in the near future.
