Religion is going to be pacified as a world power. I'm not arguing of truth of doctrine or beliefs, i'm arguing on the basis of effectiveness. In a world where people even on the most base civilian level need to have access to a world database in order to compete at all, Religion as a system of government in nations where things like the Internet are prevalent is impossible to sustain, people will find out about lies or violations of trust committed by the corrupt who put themselves in top religious positions.
This is because the idea of religion itself is based on trust, belief and values. Some people on the top will violate these things without a second thought and when anyone can be a whistleblower via anonymity, it cannot survive as a system of government because of this.
Government in these areas where religious government thrives, if they don't fall peacefully will fall violently as some have been doing now. And due to how they operate there's tons of abuses which don't help this.
Iran will likely have a shift towards a more bureaucratic form of government within the next couple decades, and the "religion of peace" bullshit will wane or fade in some fashion, though it is in the interests of some governments to try to continue that cycle in order to instill a manufacture violent revolution so they can swoop in as "peacekeepers" and gain a quiet martial control of the area.
Your healthcare isn't free or good for the record, you pay it in other fees disguised as tax, so technically you're paying for healthcare all year round even if you aren't injured, and your government doesn't care much for actually providing healthcare as loads of that money is going into politicians pockets because you let them set their own paychecks through their Senate. In America medical costs may be high, but we're not paying them all year, and it's a rare thing for anyone.
