I remember the absurdity of this book which I read it back in high school (~1977). I need to find a copy and see how well it has held up over time. Grand Fenwick gets hacked off because America is making a knock-off version of their famous wine, so this little podunk country invades us without anyone noticing. That is until they wind up with possession of the world's most powerful weapon. Suddenly they've got everybody's attention.
