Your frame of reference is too short of a time span.  The current government is very conservative and, often times, is not accountable to their citizenry, but it has not always been that way. The current political landscape, which admittedly sucks, is 100% the result of our gerrymandering in the country for our own selfish enrichment decades earlier. 

You can't overthrow a country's government, install a puppet head of state so that you can pillage their resources and expect to be on good terms with the country when they revolt in "revolution".
