As I said, if another country was doing this to America on this scale, it would be deemed an act of war. And yet somehow Americans seem to think that it's OK when they do it.
While we're talking about unfair generalizations...I would not consider it an act of war. I would want 'our boys' to figure out some way to get them to stop doing it if they can (and it doesn't cost a hojillion dollars and make us look like asses), but I wouldn't say it's cause for war. Of course, I don't speak for the U.S.; we have representatives for that.
