Peace does not need to include Muslim enfranchisement.

We could follow in the footsteps of Birhain, Kuwait and Saudi Arabia and just repress the Muslim minority (although they only do that to specific minority sects of Muslims). We could teach non Muslims to not say hello to Muslims as they do in reverse in Saudi Arabia. We could ban conversions and make heavy jail sentences to anyone who tries to convert others. We could purge communities of religions we don't like (Iran, Iraq of Christians).
