IV Islamic countries seeking power
Iran is the most dangerous militarily but Saudi Arabia controls vast Islamic networks motivated by Wahabi Islam. The nature of the ideology means that in time, Islamic terrorism will increase.
V China
China is a growing economy with a vast population. While it is unlikely to challenge the US on a fully global scale, it is hostile to US influence and seeks to back all Anti-American forces. China also is likely to use its growing military to influence diplomacy and politics in Asia thereby weakening US influence.
VI Russia
Russia's interests are highly divided with its mutual concern over Sunni Terrorist networks and Islamic separatists in the Caucasus. Russia is less concerned with Shia terrorist networks due to not facing any threats from them. This is a reversal of American concerns as the US government is more concerned with Shia terrorist groups and states than Sunni ones.
Russia is also supplying the Iranian nuclear program largely as a way to spite the US, gain money, and buy time and grace from the Islamic world as it seeks to survive on a declining demographic base.
Russia's loyal Russian and other Christian population is shrinking due to a high abortion rate, high emigration, and generally low quality of life. The Muslim population of Russia is growing rapidly and in a few decades will outnumber the Christians. Russia's delicate position is made even more so by a general antipathy to the US from the Cold War and a severe distrust stemming from extremely pro-Muslim, pro-Croatian policy of the Clinton era. Clinton's diplomatic approach confirmed Russian fears that the US was not going to act as a friend of Russia.
As things currently stand, a weak Russia can result in some terrorist networks being given free reign by Moscow, Russia supporting Anti-American governments, and other actions stemming from general hostility.
VII Liberalism (American Variant)
The Marxist elements to it and the Utopian Socialist concepts attached to them severely impede the functioning of the military, the economy, and the general peace of society. (to be continued)
