Interesting it lists right wing and left wing focus. Sounds like the US is bias towards the middle. Not sure how to groc that. Most likely it is what is important to the nation at the time would be a better qualification. History repeats itself. Thank you for sharing the links all.
The US bias when, uh, intervening in foreign politics is towards whatever's best of the US. Usually, more specifically, US corporate interests. Little care is paid to who ends up in charge so long as they're pro-"Business" and pro-America.
