(quote) Peter-449116 said: Apparently it's legal as long as that country is not fighting the US. I'm aware of the long history of Americans fighting in foreign armies including RAF pilots in WWII, but I contend that under no circumstances should American citizens, including dual citizens, fight for any foreign nation. If a man is willing to give his life for a country other than his own, he has made his first loyalty clear. The penalty should be the revocation of their American citizenship.
Just my humble
Wait, let me put on my bullet-proof vest. Comments?
Well at the very least, it should not be legal for Americans to fight for other countries, armed forces, or groups that may be at all hostile to the U.S.
For the particular cases of the Americans going off to fight for ISIS and other terrorist groups, they need to be arrested and detained and passports permanently revoked as soon that they can be tracked down. Once it is proven (that they are affiliated with ISIS), then I think there must be found some way to permanently revoke their U.S. citizenship and lock them up forever (assuming that they are not first shot for treason). They should become a man/woman without a country.
Years ago, when I worked (as an engineer) for Varian Associates, we designed and manufactured all sorts of radar systems that are used largely on military aircraft and ships for the U.S. and numerous foreign governments. There was a stack of U.S. government documentation for every single radar system sold to foreign countries to ensure that those governments were friendly to the U.S. (e.g. Britain, Japan, France, Canada, etc.) and that there was trace-ability to ensure that the radar systems did not flow through semi-friendly countries to hostile countries (like Iran, North Korea, Libya, Syria, etc., etc.). There should be no less documentation and tracking for U.S. citizens that decide to associate with our enemies.
I imagine that governments of Canada, Britain, France, etc. would want to act similarly..... But Britain and France really can't seem to get their arms around this disaster-in-the-making.
