I'm not sure closing US military bases and basically stopping to "project" US military power would be a good thing for the US or for other countries. That would just create a temporary power vacuum which other, possibly less benign, nations and powers would soon fill.
As far as I understand, Chomsky's article is mostly describing the situation and problems, it doesn't really suggest any solutions. Although it hints that the growing power of the public is becoming a benign force to be reckoned with.
