I believe you have to liberate yourself first, then you may apply the protection. If you have an incoming raid/siege, and apply it before the attack lands in your city, then full protection would protect you from the incoming.
I don't know if applying full protection after a siege automatically liberates your city-I would think you have to liberate first.
