Just stop funding it. American taxpayers have been pick up the 2% per member since NATOs creation, and even when Trump embarrassed them face-to-face, they haven’t budged.
Don't blame Europeans for not wanting to fund NATO.
America funds NATO because America controls it. NATO is an arm of the Pentagon. A way for Neocons to "project American power" into Europe.
Yes, NATO should be shut down. Should have been shut down 30 years ago. Damn Neocons.
