Hey, since we're "celebrating" the passing of CISA, here's the scenario:
It's the near future (around the 2030s, military technology hasn't advanced too much) and the United States becomes increasingly fond of surveillance and oppression. Corruption spreads among the ranks. However, their military is still very patriotic and obedient, and the economy hasn't tanked. Europe remains much as it is today, staying democratic and liberal. The United Kingdom and Scandinavia are still wary of full EU integration, however, and the euro has all but disintegrated. Their combined GDP is still above that of the US, as it is today.
Then, relations sour between the US and continental EU due to the huge difference in ideology (the EU thinks the US is an evil dictatorship, the US thinks the EU are just soft commies) and a Cold War breaks out. Former NATO allies are forced to pick sides. What are the responses of the UK, Scandinavia, Canada, Australia, New Zealand, Japan, South Korea, et cetera? What about non-Western powers, like Russia or China?
Finally, relations dip beyond the point of (possibly nuclear!) war. What event finally sparks the war - and how does it play out?
Also, I might do one of these using this thread once in a while.
Scenario 1: Orwellian US vs Continental EU
