Neutrality Amendment would this be a good idea

Robert Heilein, the science fiction writer concocted a similar scenario for one of his books. A constitutional admendment was passed (in the story) that except in the case of the country being directly attacked, gave the power to declare war to the people. That is, there could not be any war (other than response to an attack) unless the people voted directly for it. Additionally, all those voting for the war would be immediately drafted and sent to the front. BINGO, no more wars, at least in the book.

I do. part of the reason the US is unpopular world wide is due to US "Imperialism" I think it would be best to take a low profile in the world. Something like this amendment would help to avoid a future Iraqi mess.

Maybe a little too inflexible. We no longer live in a world where a country like America can just pull up the drawbridge and expect to be kept safe by the Atlantic and the Pacific. There could be a future time when a major power comes to dominate the rest of the world by knocking over one smaller country at a time, until America is both isolated and vulnerable to direct attack, and if you've got no allies...
