The Eurozone Military
Our citizens must be told to expect pain. Pain in the form of economic repercussions. Europe must be weaned off of Russia's natural gas and at least in the short run that means we must share in the increased cost of energy that will occur in Europe.
At the same time Europe must step up and agree to bare more of the burden on their military defense. We assisted our allies in many ways to recover from World War II and the Korean War. We helped rebuild Europe. We defended the "free world" from a takeover by communism and we helped their economies by entering into trade agreements that did not always help the American citizen.
