It is theorised that Russia is the way it is due to the psychological trauma of the mongol Conquest

And similar things exist in the United States of America being traumatised due to race relations and the impact of slavery

Which is very unique to the American experience and cannot be applied to the rest of the world

Also the American War of independence 1775 to 1783 was also highly traumatic it's why as a culture when it comes the Britain they had bad Daddy issues

Their is also the right to bear arms which also comes from that experience as well as a massive mistrust of a central government

It's what makes America America for better or worse

China still has trauma from its own mongol Conquest in the 13th century and why China regressed in the 15th century

Their is also the impact of its founding in 222 BC with Chinese legalism and the bureaucratic state as well as the political culture

Which still exists after over 2,000 years even during communist China
