It's 'ok' (as you put it) for them to support their respective allies.
But despite your love for Biblical references, pidgin babble and pretend 'genocides': do you really aspire to a world overrun by theocratic rule and clergy that limit personal freedoms, like in Iran? Fanatical patriarchs who suppress (non) religious and individual freedoms especially that cause abuse of women and children.
It might be 'ok' for you if you envisage a world consumed by Islamist regimes and their warring proxy terrorists groups, inside and beyond their boundaries, like those throughout the Middle East and Africa as a model.
But realize that the citizens who have to live under these regimes are not AOK.
