Step 1: expand the European Union
Step 2: integrate the European Union so closely that it becomes a single country
Step 3: the expansion of BRICS+ and so forth forces a shift towards local manufacturing in Europe, growing the power of the country's working class
Step 4: A massively unpopular leader forces Europe into a massively unpopular war with Russia, worsening economic stagnation and exploitation
Step 5: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
Step 6: All of Europe goes red at the same time
