West Coast, you are quite right to castigate European nations of NATO who do not pull their weight in contributing to their common security. With respect though, I think you are quite wrong to characterise NATO as an anachronism. If there were any doubt in the USA as to the lack of merit in a policy of isolation then that should have been settled by WWII. If the USA had remained neutral would it even exist now? Very little has changed in real politick since then, whether in the threat to Europe or the Far East. The threats may or may not come from different capital cities but they are as real now as they were in the 30s. Because we prevaricated then we had together to fight and defeat them in the 40s or confront them together for another four decades.
This is no time to prevaricate either. The EU Grand Projet is built on hubris, NATO is built on a mutual need. Because Berlin and Paris can't see that yet is no reason for Washington not to see it. Together we are stronger than apart and should stand together!
