The world's people see that globalism is what turned a US economic mess into a global catastrophe. Selling them more globalism as a solution is going to be tough.
What happens if there is only a single global government the next time a Hitler comes to power? Or a Bush? Who will stop them from declaring a particular group of people as no longer necessary to the smooth functioning of the planet and ordering their "erasure?"
Look how badly our leaders have run the country. Think they will do any better with an entire planet? If a kid crashes his VW, do you allow him to drive a bus as a reward?And yet the US Government can spend tax money on bailouts for the rich, weapons of mass death, torture prisons across the globe, and of course, billions to Israel.
