After reading this article, I'm keeping my eyes open. They're my buddies, and I hate to be paranoid, but I'm sworn to defend the country against all enemies.
Disturbing trend. When I was in the service (late 60s), non-citizen soldiers were few and far between.
IIRC, Rome fell largely because its army was composed almost entirely of non-citizens. Its citizens were too wussified to serve themselves and its non-citizen soldiers had nothing invested in the society and weren't about to die defending it. Of course, it's much worse if the enemy is actually infiltrating the army.
Multicultural RAT-ism is to blame for this. Damn them.
