What if the majority of the country supported the president the rioters are trying to oust?
For example, the majority of America elected President Obama not once, but twice. What if 30,000 or so rightwing extremists ascended on Washington and started burning things down? Should the government listen to that minority block of people over the millions that make up the majority?
You see, the Ukraine president might very well be listening to the people. I have to wonder what % of the country these rebels represent.
A government can't let the wants and desires of a handful whiney pukes over ride the will of the majority. Even if they do start throwing malitov cocktails.
