The problem is we would be throwing the baby out with teh dirty water.
NATO is not just France and Germany. Several countries in NATO that are pulling their weight would also be abandoned... (EG Latvia, Lithuania, Estonia, Denmark, Poland,...)
No! The problem is we need to remove the baby from the basin and dispose of the filthy water and refill the basin with clean water. i.e. dump the moochers and let them fend for themselves and retain the true allies.
