neo con stands for Neo-Conservative, or "new" conservative. It represents the current Republican party in the US. People, like GW Bush, who call themselves neo cons believe that God almighty has made the USA the most powerful and wealthiest nation on Earth so that the USA can lead the rest of the world. They also believe that the USA has the right to stick its nose into any foreign locale to right what they see as wrongs.
This is similar to the insane notion of "Manifest Destiny," which was believed by most, if not all, Americans in the 19th Century. Manifest Destiny is the belief that, yes, God wanted the entire continent of North America, or at least the good parts, to belong to one country under the control of the United States of America. This ludicrous justification was what drove Americans to conquer the West and genocide over 10 million indigenous people. This fantasy is still taught as fact in US schools to every 3rd grader, but they mostly skip the part about the genocide and focus on how God chose the USA to tame the West.
