National defense is a classic example of a public good as it is non-excludable (protection provided to citizens cannot be restricted to only those who pay for it) and non-rivalrous (protection provided to one person does not diminish the protection available to others). This means that national defense is difficult to provide as a private good because it is not profitable for providers to do so and it is difficult to exclude those who do not pay.
