My guess would be that the OP subscribes to the MAGA worldview, because in their alternative reality, the US-Europe security arrangement was not a mutually beneficial relationship between allies, but a parasitic relationship where the US pays, and Europe reaps the benefits.

Obviously, this worldview is strategically myopic, based on ignoring many things the US was getting out of this arrangement, like US military bases in Europe (also used for power projection to the Middle East), Europeans buying US weapons (big part of why those weapons are so advanced), doing America's bidding in the UN, supporting US military adventures (however misguided) in Iraq and Afghanistan, etc.

It could be argued that the US role of being the security provider to Europe and others was the main source of their wealth and power. The US had the proverbial goose laying golden eggs, but Trump got angry that they had to shelter that goose, so he kicked her out... no goose would abuse the US like that!

Here is one example: Trump saying that the EU was formed to screw the United States: https://www.youtube.com/watch?v=9kq28VSlvUw

Indeed. I am also tired of Trump pretending trade imbalance is real when he is only counting goods and energy, but he does not count the massive influence of American Big Tech and how Europe basically has zero competition against cloud services, operating systems, office suites, mobile phone manufacturers, computer chips... It all comes from USA, or, lately, China.
