Yes, you're pretending to be a 'realist' who is wise because of your grounded worldview, but you totally miss the forest for the trees: if we don't want to end with blowing ourselves up then we
have to depart from the might is right and 'how the world is' mentality because that stops us from changing into a future where we will not blow ourselves up.
Your worldview is essentially a pessimistic one, mine an optimistic one: I think we are capable of change. We just make the stupid mistake of putting egomaniacs in positions of power all the time and then we are surprised by the outcomes.
Some of the most powerful words ever spoken in American history were 'I have a dream'. Dreams are good, especially if they are dreams of a better world and we all should strive to create that world, not to declare it a pipe dream and get on with the business of raping each other.
