We're not the United States, able to enforce its will on much of the western world. We survived, at times barely, a war that destroyed millions of people and drastically affected society. And we felt being aggressively militaristic, or biased towards one state over another, went against the history of our nation, and the U.S. state it had been since the late 18th century. Neutrality fits our people well, and we feel the advantages, in every area from cultural to business to political, far outweigh the disadvantages.
