okay, most of this story, you dont know, I have other things like a comic and stuff that goes along with it, explains much more than this animation does. This animation is just showing some fighting that is going on and personally i dont think many people HAVE to know the storyline but for those who do:
4 main superpowers: Asian Confederacy, Russia, United Allied Federation, and the European Union
year of ww3 starting: 2065
After and extremely large amount of oil was found in parts of alaska, the US became the largest exporter and the economy grew to epic proportions. Russia, Jealous of the US at this point tried to buy land off and use diplomacy to try to get a cut. Each time Russia being denied. The AC was increasing it's army by the thousands. All other superpowers became frightened and catious the AC's. The European Union had a new leader elected. This one hated much of the other world and wanted the UK to join into the EU. And the Us was still fighting many wars it shouldn't be in.
At some point in time nuclear blasts went off in many major capitals in the world. This sparked outrage amount all groups and after years of mistrust and paranoya, finally snapped.
Russia invaded Alaska for the oil, AC saw this as a weak point for Russia and attacked Russia, EU invaded the UK and Russia, and then soon after fully conquering the UK, invaded the US.
yadda yadda this and that happened, and Russia and the US realized they couldn't fight a 4 way war and called a ceasfire between the two. eventually leading to a temporay alliance and counter attackes.
The second space race is to get a manned aircraft outside of our solar system
