Because they were in power!!! They can do anything to get into power and then earn money. Come on do you really believe that they are nationalist ? I can never imagine a political party in US that is based on the ideals of the assasin of Abraham Lincoln. While we market ourselves as a democracy, all we have to our credit is that we conduct regular elections. These tathagatha types are just frustrated souls who are essentially losers in life and frustrated by their own community.
