Assertion: Protecting citizens from foreign attacks is sufficient to maintain the security of an individual.

Reason: During the last 100 years, more people have been killed by their own governments than by foreign armies.

The Assertion is incorrect but the Reason is correct.

Non-traditional notions of security go beyond military threats to include a wide range of threats and dangers affecting the conditions of human existence.
Non-traditional views of security have been called ‘human security’ or ‘global security’.
Human security is about the protection of people more than the protection of states. Human security and state security should be — and often are — the same thing. But secure states do not automatically mean secure people.  Protecting citizens from foreign attacks may be a necessary condition for the security of individuals, but it is certainly not sufficient.  Indeed, during the last 100 years, more people have been killed by their own governments than by foreign armies. All proponents of human security agree that its primary goal is the protection of individuals.
