The 19th century anarchist philosopher Bakunin wanted to see Siberia seperate from Russian Empire, ally with/become part of USA and than "spread democracy" from the East to West.
So here is a challenge based on this: with a POD after 1800 AD, have USA and Russia enter a union by the year 2014.
Some caviats:
1) Russia should have at least its modern (2014) borders (& lets mot get into a debate over Crimea please).
2) Ideally Russia should still be a monarchy.
3) By year 2014 the US-Russia Union should be at least as integrated as the OTL European Union. Ideally, they should be merged into one nation.
So, lets see you give it your best shot!
