Patriotism does not mean that you think your country is perfect, or blameless, or even particularly likeable on balance; nor does it mean that you serve it blindly, go where it tells you to go and kill whom it tells you to kill. It means that you are committed to keeping it alive and making it better, that you will do whatever seems necessary (up to and including dying) to protect it whenever you, personally, perceive a mortal threat to it, military or otherwise.
