NATO’s problem is not that it doesn’t pay us protection money. Its problem is that NATO nations don’t invest in their own defense to maintain their defense capabilities. The reason for that is that nearly all the NATO nations have joined with other nations outside of NATO in the European Union, which competes directly for defense dollars by imposing its multicultural policies that require massive investment.
