I never agree with this line of reasoning. Has the US ever installed a 'puppet' government for the benefit of the US? Sure. Does it happen every time the citizens of a country protest and oust a current dictator/leader? No.
Which country on earth has the oldest democracy? Let's suppose you just took control of a country (as a citizen of said country), and the reason you are in control is because the people want a democracy. Who would you call on for guidance? Who may have some insight on how to establish and run such a system of government?
This is not a US generated or led uprising/ousting. This is home grown, and that's exactly why Russia is in the Crimea right now.
