My father was born in Hawaii in the late 1930s. After war was declared in the Pacific Theater, they had to cover their windows to block the light, couldn't really drive at night, and take other steps to prevent becoming a target of Japanese bombers.
Some of my father's close friends were interred in war camps. They lost their property and their dignity, even though many were born in America (my father's side is Japanese).
My father is very protective of America. He is quick to bash countries that don't cooperate with our government's officials, no matter what the policies. He's wary of immigrants and their effect on society...I think this is somehow rooted in how Japanese Americans were treated during WWII, i.e. are you with us or with them? I don't think it has anything to do with his drinking, though my dad is a lifetime beer drinker/abuser. My father also joined the military before college, perhaps in an attempt to help pay back the country that protected him in Honolulu, or maybe to prove he was truly American, or maybe just to see the world.
