Well, a country has to protect its laws.

It has to either restrict propaganda, or be prepared for slaughtering hordes of brainwashed zombies.

Of course, in can just give up, and let a new government take over peacefully.

International community believes that restricting speech is better than killing zombies.

The constitution needs a protector. The king, the people, faith.

People can be corrupted with greed and decadence. Faith can be lost.

Nothing lasts forever.
