Global Secular Government

The idea of a global secular government is completely absurd, and kind of funny actually. Just the thought of everyone in the world cooperating with each other and living in harmony is a huge long shot and fantasy, just like John Lennon's song, imagine. There is so much corruption in this world, the only way for a utopia to happen is if groups of radicals were destroyed and every country in the world gave up their power and leverage over one another to establish one government, just simply won't happen. Also the fact that there will be lots of rebellion as well as contradicting world views, lifestyles, and ethics that will cause people to clash rather than live in peace.
