I mean, this is an incredibly disingenuous conclusion. By that logic democracy is flawed and can never exist in South America, the Middle East, or any other number of places where the CIA staged coups and assassinated leaders.

It's hard for any system to thrive, regardless of its merit, when the world's de-facto superpower has dedicated billions into its destruction.
