Wow this is some pretty cool feedback! To address some issues that came up. Particularly the formation of the NAN. Ok I agree that I have a BIG problem with the NAN formation from a logical standpoint, but like someone else said in this thread you can't get rid of them or the Great Ghost Dance without seriously altering the world. So basically I changed some of the reasons behind its formation and what went down.
Changes:
Sovereign Tribal Council does not order all “Anglos” (Can't run a country if you ask 98% of your population to leave) to leave North America, only that they adhere to the certain “official” treaties that were made with Native Americans by the United States government.(basically after the Trail of Tears). This is what the Treaty of Denver is based on. This argument goes along the same lines that Israel uses for its justification of having a country, England promised us this land after the First World War and because the Torah says we are God's chosen people. Same thing with the STC except they site the treaties made with the Jackson Administration, I can't remember what it's legal name is but something like "we were here first" (It's actually pretty interesting because back in the early days of the US the Cherokees actually brought a case like this to the Supreme Court, and the Chief Justice said that the Native Americans claim was invalid because they did not have the concept of private property in their culture so therefore that didn't have any property rights to their own land. And since whites did have that in their culture then they could claim the land. Talk about the man screwing you!)
The reason that the US came to the table in the first place is because of the Great Ghost Dance. I changed it to where people were really, really afraid of magic on that scale at this time. There were doomsayers in the government that really thought that the Native Americans could blow up the world. (Basically like the Japanese thought the Americans in WWII had more atomic bombs when we only had the 2 on hand.) Then you also had those politicos that supported the Native Americans, and were sick of the way that America had treated the Native Americans and they had finally had enough (and if you don't that's possible then you need to read some articles about those Americans that got into Baghdad to try and stop the Americans from bombing it this time around.)
So the Treaty of Denver was backed by the UN, mostly by China, France, Japan, and the Soviet Union (Yes they were still Stalinist communists. I basically wrote it that the hardliners actually succeeded in ousting Gorbi (which they did) and retained power.) and certain “left” elements in the US that agree with the NAN’s Green Policy. President William Jarman becomes the first president in US history to be impeached. Jarman becomes the scapegoat for the "collapse of our great nation, and our role as a superpower". (Wow! imagine Americans putting ALL the blame for their country's woes on the President!

)
2031, The Euro-Wars, NATO/Soviet Union war begins. The UCAS gets involved to defend Germany, due to hawks in the Southern portion of the government that remember Germany being the only vocal proponent for the United States during the Treaty of Denver. (Now this may seem a little farfetched, but not really. When you have problems at home, you need to find a war, and fight it. Why didn't they invade the NAN? Well the UN was protecting their status as a new nation, without the help from China and Soviets as they were really getting to invade Europe and Japan respectively. Plus the UCAS honestly thought they would come crawling back. It's the mindset of "Hey why would anyone want to leave this great country? They will come back! But first we have to go get those commies. They were the cause of this mess!) The war lasts three years with a high body count, and the Soviet Union collapses and China erupts into Civil War. Politicians in the North and Canada began to pass legislation and welfare reform that borders on socialism (Canada), and because of the bloody conflict in Europe, which now many people see as pointless, but not everyone, they call for the downsizing of the military.
The states of the SR CAS leave the UCAS and begin to set up their own government. Since SR uses history as a model for their world I basically wrote that the reasons for leaving were much like the ones in 1861, which is over politically differences (now before any of you get upset, I am not saying the CAS is the CSA. They don't have slavery and this is not the rebirth of the Old South. People in the CAS actually see themselves as "the only real Americans". They feel that they left because of unfair taxation and tyrannical government, basically using the arguments that the revolutionary fathers did.)
March, 2035 – Jan, 2036: Aztlan invades Texas. Aztlan leaves the NAN and then attacks Texas. No Texas does not leave and comeback to the CAS, and Aztlan does not take Texas all the way to San Antonio. CAS Special Forces and Partisan citizens kick some major ass and push them back across the Rio Grande. Aztlan asks the NAN for help to which they say "Go F**k yourself, you left on your own, you made this mess, clean it up yourself." (I am sure the actually diplomatic correspondence was a little more tactful but you get the idea).
April, 2036 – March, 2037: CAS/Tir Tairngire war: California is kicked out of the UCAS. Tir Tairngire invades, but the CAS offers statehood, to which California accepts. The CAS declares war on Tir Tairngire and the shooting begins. CAS pushes the elves out of California. (The reason for the wall). Again Tir asks for the NAN's aid and they give them the same reply as Aztlan. Because of the way the CAS is handling itself with two wars and the UCAS's lack of helping California the states of Maryland, Delaware, the rest of Virginia, and Kentucky leave the UCAS and apply to the CAS for statehood. The CAS moves its Capital from Atlanta to Washington DC, and the UCAS moves to Philadelphia. (One of my gamers asked me why the CAS didn't just go back to being the USA. I said basically it was an image thing, the mytho-poetic rewriting of history. They want to keep all the good stuff from American history and the individual Southern Spirit, while trying to downplay the negative. "See we are the USA, but we don't kill Native Americans like the USA. We believe in State government over Federal government in the CAS, but we are not the CSA with slaves and all." It's complicated and somewhat over-simplified much like the historical perspective about my country's (USA) past today.
April, 2037 – April, 2039: After months of negotiation with the Japanese Imperial State on the removal of Japanese Divisions from San Francisco and Hawaii. (Japan sent in the Marines to protect "Japan citizens and property during the Tir war". No California did not ask for aid, Japan just did it, trying to grab a slice real quick, but they underestimated the CAS's resolve) The CAS makes a surprise raid on Pearl Harbor and San Francisco. The Japanese Imperial State appeals to the UN for aid but finds that it has no friends. Germany joins the CAS in its war against the Japanese Imperial State. Soon there is fighting in Southeast Asia. (The CAS fights the Japanese in China, the Philippines, and Vietnam in order to shift the fighting away from the home front, and to bring it to Japan's backyard.) The war ends with really no clear victor in terms of gain, but the CAS regains control of California, and Japan agrees to buy Hawaii.
August, 2052 – October 2052: CAS invades Cuba to “uphold its sovereignty” against Aztlan (who actually made plans to invade it first, but were actually 2nd, as the CAS had covert ops teams in country the day before the invasion.) Most of the government is killed in the fighting (This is due to the CAS but the blame is laid against Aztlan.) A provisional government is set up, and in December 2052 they formally ask to be let into the CAS. (Basically the CAS was backed by SK and Ares. They wanted to block Aztechnology's attempt at expansion, and I wanted to turn Cuba sort of back to the way it was before Castro. You know with the Mafia and Casinos, but with Megacorps too!)
The CAS is composed of 20 states: Florida, Alabama, Georgia, Mississippi, Texas, Louisiana, Tennessee, Virginia, Maryland, Kentucky, Delaware, Arkansas, Missouri, Oklahoma, New Mexico, California, South Carolina, North Carolina, Puerto Rico & the Virgin Islands, and Cuba
Ok why did I do all this? Because my guys like to play Special Forces and Intelligence (CIA) type games. Differences in this world from SR
1. CAS Special Forces are the best in the world. They have been in more wars then any one country in the last thirty years and with bases such as Ft. Benning, GA, Fort Bragg, NC, and Camp Lejeune, NC they have the tradition of Special Forces more so then any country in North America.
2. The CAS takes a definite foreign policy shift from the UCAS. CAS does not have a Secretary of Defense, they have a Sec. of War. Their policy is something like George W. Bush's, pre-emptive maintence. Unlike the UCAS, which doesn't want to get involved in anything that might cause themselves trouble, the CAS takes the attitude lets keep the opposition busy so they won't become a problem later. However they do not have the resources to invade and occupy countries, plus that is a little counter-productive since imperialism doesn't really work except at pissing native populations off. So instead they train guerillas and rebels and run Black operations against anyone they perceive as a threat in the near future. Again this is done with intelligence agencies and Special Forces.
3. Yes the Megas are powerful but they do not like fighting big wars and running governments (Wars and governments are a money sink, and corps are in business to make a profit. Now wars are profitable if you are supplying the guns to a government, but if you are fielding troops then, no.) Yes they do have military forces of their own but is more to uphold extraterritoriality and keep the wolves at bay (other Megas and governments).
So no the Sioux Wildcats and the Tir Ghosts are not the best in my game. Yes they are highly trained and yes they can kick some major ass, but CAS has the edge because of veteran experience and tradition.
Well sorry for this long piece. Just thought I would share my little view of the world since many of you were kind enough to share yours. Thanks for reading it.
