Sure, but it's not reasonable to call it as unpopular domestically as the Vietnam War, which had more than 12 times the casualties, spread over a group that on the whole was unwilling to fight and had to be drafted into the conflict, thereby spreading the pain of lost loved ones throughout society rather than concentrating it heavily into the poorer and less politically powerful social and economic classes. As unpopular as the Iraq war was, the American people's distaste didn't really do much to end it.
