Yet it seems to me that Euro decline is no great complex mystery.

Corporatism -> Consumerism, Nihilism & Hedonism -> Waste, Eco-disaster & Birth Rate crash->Ecoscams, etc etc.
PC Feminism & Multiculturalism.
Government Corruption & “Incompetence”-> Waste, Corporate Welfare and Banksterism.

American and Euro support in every way and for all decades for Stalin and Mao e.g. allowing Commie Jew and Chinese spies to give the nuke to Stalin and Mao.
Continunal Wars and the Militarised USA. There are not many fundamental differences between USA and Europe.
American and Euro tax-subsidised technology and manufacturing base transfer to China.

All driven by Rothschild, of course. All planned by Globalists, most of whom knowingly jump to the Rothschild tune, the ArchJews.
Where is the mystery?
