You are right about options but wrong about motives.
The time was right to break free. Election camadarie would not work in their ruled states. Word has come of their campaign efforts.
They are frankly admitting they did not quit because of the nuclear deal but the lack of transparency (remember lies by Pranab)was the last straw on the people's back. Previous bushels were inflation, etc, etc. which the people are eating up.
I admire their political (not developmental) strategy which is better than the others. Isn't it all about politics.
But for lack of a better choice, they are the rung holders, stirrup standers and lash abusers. They cannot take anything further or initiate anything. They are traitors but they are doing all the correct things.
