Gracefully UPA should request the president to dissolve the present parliament since their supporting parties deserted/ditched them now. Congress should seek votes on that N-deal issue and come back if possible.
The present scene in Delhi looks like events those took place before Kurukshetra WAR. I do not know whom Dharma ( then Krishna) is going to support. Presently the WILL of people (invisible and innocent in appearance) is DHARMA/their bad karma. It is watching and patiently waiting.
