NATO’s mission ended with the Cold War ending in 1991. It has staggered along with no real purpose the last 25 yrs. If it is to continue a new mission and purpose must be decided upon, a purpose that must be in the USA’s national interest.
All the western European countries have lived off our defense spending for 70 yrs. and wasted all their resources on social programs. Time to pay up Europe or be turned to slaves in Eurabia.
And it was after 1991 that NATO expanded into places where there was absolutely no US interests.
None.
