It's certainly not "backed by the west". These dictatorships exists because they allow the elites to exchange the profits from the sale of natural resources in exchange for dollars and euros.

The most effective way to punish regimes would be to: - take away (arrest, freeze, whatever) the elite's real estate in the west - same thing with other assets, banc accounts etc - ban them from living in the west or going to the west on vacation, for medical treatment. - ban their families from living in the west, their kids from studying there. this is not my idea, you will find similar…
