Well we just saw this am how a strong government can solve the problem you mentioned, just buy the pipeline and the project to twin it. There seems to be no doubt that the potential return for the taxpayer is significant. The idea of world government has been around for centuries all the way back to the Bronze Age of Egyptian Kings and the Han dynasty in China. Of course nationalism is a strong force against the idea. And if you don't think that is often self serving to a fault I will leave a quote from someone who was also a proponent of world government even before he had to suffer at the hands of nationalism. You may have heard of him.
”As a citizen of Germany, I saw how excessive nationalism can spread like a disease, bringing tragedy to millions,” he wrote in 1947.
Albert Einstein.
All the ideas of world government have come from those who see themselves as governing it, including Einstein's reference.
