There is a civil war in the United States that starts in 2005. That conflict flares up and down for 10 years. In 2015, Russia launches a nuclear strike against the major cities in the United States (which is the "other side" of the civil war from my perspective), China and Europe. The United States counter attacks. The US cities are destroyed along with the AFE (American Federal Empire)...thus we (in the country) won. The European Union and China were also destroyed. Russia is now our largest trading partner and the Capitol of the US was moved to Omaha Nebraska.
One of the biggest reasons why food production is localized is because the environment is affected with disease and radiation. We are making huge strides in getting it cleaned up. Water is produced on a community level and we do eat meat that we raise ourselves.
After the war, early new communities gathered around the current Universities. That's where the libraries were. I went to school at Fort UF, which is now called the University of Florida. Not too much is different except the military is large part of people's life and we spend a great deal of time in the fields and farms at the "University" or Fort.
The Constitution was changed after the war. We have 5 presidents that are voted in and out on different term periods. The vice president is the president of the senate and they are voted separately - Jon Titor - History of his Alternate (but probably similar) worldline
Not that John Titor is really a world-line sifting time traveler I am just entertained by the idea.. but it contains a salient point..
so, lets seriously consider this-- If you watch Putin's recent speeches, how is he trying to present himself to the world?
Some examples:

http://russianforces.org/blog/2009/10/new_russian_doctrine_and_preve.shtmlhttp://thebulletin.org/why-russia-calls-limited-nuclear-strike-de-escalationIf Putin wants to continue projecting this image of himself, and were to launch a nuke strike against the US- would it be a full strike or tactical?
Is Obama likely to respond with a full strike in retaliation ( assuming he survives) or would there be a stand down order? ( I think Putin would have to ensure the moron survived..)
If the targets were say , low yield nukes on Washington DC and New York City, what would be the response of the citizenry? Would it mimic John Titor's in that we would recongize that the power centers of the "other side" of our culture war had been destroyed?
Here is a fun site to help you figure that out
http://iSideWith.com/map/dAWYou can see geographically party affiliation, support for gun control, support for Obamacare... and percentages..
And here you can experiment with different nukes, altitudes and blast radii, in case anyone doubt that this can be done tactically.
