Religion plays a role in violence and war, but it seems to be more of a tool used to motivate and mobilize rather than a cause of war as Maher suggests. The real cause is money and resources. Countries that despise America don't do so because their religion dictates they should, instead, they are typically countries that have been repressed by the US through economic means, or if that doesn't work, through warfare. then religion can be used to inspire individuals in the military. we do the same thing in America.
America has been trying to stay on top... partly by keeping other countries down. but it is not sustainable. The consequences will be very difficult to survive. the people's financial support is the real influence, we need to learn which companies are committing these global crimes, the same companies that are keeping our government in their pockets, and we need to stop supporting them unless they regulate themselves.
it will require us to make sacrifices to our material possessions and our energy consumption, but the alternative is to just sit by until we lose all of those things entirely, which wont be long at our current rate.
