Protectionism/isolationism does not work.You can also add to that list the trillions of dollars we spent in world wars 1 and 2 and the cold war to keep Europe free. Also, don't forget about the U.S. rebuilding Europe with the Marshall plan. The reason they have all those generous social programs is because they didn't have to pay for their own self defense, the U.S. defended them at the expense of the U.S. taxpayer. If we had let Hitler or the Soviets have them, we as a country would be trillions of dollars richer. I find it amusing that the Europeans consider us arrogant since they were the ones who wrote the book on it. Lets take a brief look at European history: Hitler, Stalin, Napoleon, Cesar,the French empire, the British empire, the Spanish empire, the Roman empire etc. You are correct about our charity to the world in the form of money, time, and skills; we are by far the most charitable country on Earth. But there are many who dislike us for a variety of reasons; our success for a relatively young country and our unwillingness to apologize for it, our concept of the freedom of the individual, our concept of allowing individuals to enjoy the fruits of their labor to the greatest extent possible, our freedom of speech, etc. I think it is time to stop international charity and defending other countries....yes, if they insist that we are bastard$ then let us indeed be bastard$, let us withhold ALL our generosity and see how well they fare. Let us be isolationists and say "to hell with the rest of the world". When the next dictator overruns Europe or another continent, let us just give them "the finger". The U.S should withdraw from NATO and every other alliance, this would save hundreds of billions of dollars. If we were to cease all foreign aid and private charity we could save hundreds of billions more; we could pay off the debt Bush and Obama have run up quite quickly. We only need to defend our own borders. Let everyone know that if the U.S. is attacked nuclear weapons will be used in retaliation, we used them before and we can use them again.
Look to the past.
