The alternatives to theocracy around the world don't work
While there are many systems of governing aside from theocracies, they are not preferrable.
North Korea, USSR/Russia and China have little religious influence. In fact they have a history of suppressing religion.
In some countries, there is a political ideology sponsored by the government that may be called political religion.
For example the North Korean government has promulgated Juche as a political alternative to traditional religion. The doctrine advocates a strong nationalist propaganda basis and is fundamentally opposed to Christianity and Buddhism, the two largest religions on the Korean peninsula.
[P1] Having a theocracy is preferrable to having a regime based on political religion.
