The Iran-Afghanistan-Pukistan-India Gas Pipeline will be a terrible disaster.
1. All of them demand extravagant rates for allowing the pipeline thru their countries. 2. Iran's price demand of gas is extremely high. 3. All those countries are infested by terrorists who don't think twice before blowing up vital installations. India should be ready to face pipeline blow-ups and disruptions and be ready to shell out consequent repair charges. 4. Apart from this, all these countries will steal gas from the pipeline and blame it on fake terrorist attacks too.
Most dangerous point is that Congress is very adamant in this deal with Muslim countries, only to get Muslim votes in Indian elections.
