Israel has Nukes for years now,which country in ME was threatened due to that.
Pakistanis clapping their hands on Iran developing a nuke has to realise that Pakistan is closer to Iran than Israel.Iran emergence wol dundermine pakistans importance in Islamic world and increase the tensions too.
Pakistan recently said they support Iranian nuclear program for peaceful purposes, and even if Iran does get Nukes., I hardly doubt they will use it aganist a muslims country knowing full well pakistan can strike them in a heart beat. But Iran getting a nuke is good in a way that it will calm Isro ambitions down for a short amount of time to build up the army, etc.
