With respect to invasions by foreign powers, yes. But neither the government nor the police can be expected to actively protect individual citizens. Protection via deterrent forces (e.g. laws against violent crime) is all the police and government can really do. If you want to actively protect yourself and your family, it's your responsibility to do so. Outsourcing that job to the government and police is how we got to a our current state--they can't "protect us" without sufficient power, which we readily handed over.
