That is an out right lie. Got it straight from Mirram Webster. You have yet to provide one ounce of proof that the countries you mentioned were pure socialist. As they stand, they are hybrid systems. A mix of capitalism and socialism.
I don't think we need to. I think you intentionally focus on the worst aspects of socialist history from 100 years ago while ignoring the modern day success stories because it suits you.
You also intentionally ignore how socialism made America what it is today as well.
