Maybee one day we could have a world with one government. No wars fought over nationalism, No third world underpriveleged countries, one world army only there to keep the peace, equal rights, no detention camps where prisoners are kept and tortured under suspission only no trial, no genocide left to thrive while the UN sits on it's asses cause they're busy worrying about the little issue's their country is having.
Most of you probably won't agree with me, and sadly this will probably never happen unless the world faces a huge devastating change (maybee like when we send ourselves into the next ice age) but I believe we would truly become an advanced civilization if we all united to work towards global equality, peace and happiness.
