rrocket and unctuous,
The question is not who makes the best cars, or whether US cars are competitive with Japan's best (or Germany's best), which is the point rrocket seems to be arguing. The question is whether someone who refers to Germany and Japan as "the enemy" has (a) been living in a mineshaft for 60 years, or (b) is just plain crazy.
Germany and Japan were our arch-enemies for about five years, sixty years ago. They've been some of our best-buddies, though, ever since. If you're 70, and you hated someone in high school but have been best friends with him ever since you to graduated, is he your "enemy" or your "friend"?
I've got no problem with boycotting cars from a hostile power. If Osama Bin Laden sold a flying car that ran on CO2 and produced nothing but puppies as exhaust, I wouldn't buy it. I do have a problem with someone who calls a good ally--a good ally for sixty years--an "enemy" because, sixty years ago, we had a war with them.
And unctuous, don't even think of lecturing me on WWII war crimes. I'm Jewish and you're not going to tell me anything I don't already know. But today's Germany is not the same country as 1944 Germany, which is why I have no qualms whatsoever about driving a Veedub.
