"I voted according to my beliefs"

So finally we have the nuke deal on track. For months a lot of esteemed and not so esteemed people have been debating about the deal which was struck in 2005 between Dr. Manmohan Singh and George Bush to no definite conclusion one way or the other.
I purposely use the names of the personalities here and do not mention the countries because I am not sure whether the countries really signed on the dotted line, metaphorically, ofcourse a country is not a living being so she cant sign anywhere. A country is represented by the leaders and it is they who put their initials whenever and wherever it is required in place of the country. Hence it should be the moral duty of these leaders to do something which is good for the nation as they are not initializing as individuals but as representatives of the nation.
However with this new deal I am not so sure whether India was represented. Please do not get me wrong - I am strongly for nuclear energy and whatever is required to make it a feasible and sustainable source of energy. But like most of the fellow Indians I am in dark about the details of the pact. Being fortunate enough to be an educated individual I do appreciate the fact that renewable sources of energy are crucial for India and anything which ensures constant supply of fuel for our reactors as well as latest technology to upgrade the facilities should be welcomed. Inspite of this an option to understand the pact in detail would have been appreciated not just by me but also by all.
So I went by common sense in supporting the deal however after watching the proceedings of the trust vote being streamed live from the Parliament I did realize common sense is not so common. It seems 275 individuals voted to keep the government in power and 250 odd individuals to keep the government out of power and I thought the vote was about whether we should go ahead with the deal or not. Less said about the people voting the better. All voting for the government and all voting against, went from TV camera to TV camera ( pillar to post eh?) claiming that their vote is based on their conscience and their strong beliefs - it was just incidental that they are getting to become ministers, chief ministers, getting cash in suitcases, airports in their names and so on.
To summarize it in word the whole "tamasha" was shameful with the players being as shameless as ever. Our MPs again made a laughing stock of our country. Where was their common sense? I am not expecting them to know the details of the agreement but is it so difficult to understand that our energy needs are rising and fossil fuels cannot sustain them for long? In metros if the monsoon fails there are power cuts for 6-7 hours then what can be said about the interiors? If they had decided to vote on common sense then maybe this whole "tamasha" would have been avoided.
The question which comes up though is that who sends these people to Parliament - is it not us - are we also voting according to everything but common sense?
