Hanging of Afzal Guru

Initially even I was confused that why is Afzal Guru still alive? He has been convicted by every court including Supreme court. So why is he still alive? Many have this question including the opposition but I believe that given the circumstances any party in power wont be able to hang him.

Everyone will know that there is a similar prisoner Sarabjit Singh who is convicted of bombing in Pakistan and has been sentenced to death by their Highest court. I know many will shout at this point that both cases are different, but thats just point of view here. They wont be feeling the same in Pakistan.

So what happens if Afzal Guru is hanged tomorrow? I know Pakistan does nt acknowledge Afzal as their own, but we can all assume where their heart lies. They'll obviously want to give a reaction (like everytime an Indian missile is tested, withtin a week Pakistan missile is tested). So we can all guess what their reaction will be. I know no gevernment can directly give the reason of why its delaying the hanging but no government can also hang him and allow death of Indian citizen.

So it would be much better to understand this than make an embarrasing position for any party in power by questioning again and again.
