The purpose of second strike would be to cause severe damage to the Paki's or lizard military/ economically important areas . In case of Pakistan it would mean a huge portion of their military and industry because not much exists in the name of it. In case of PRC it ll mean a sizeable portion of their economic regions and some military ones. In case of China that would be a good enough deterrent. Because they give importance to their economy unlike the Paki's . China's ultimate aim is to become a superpower. And beginning a nuclear war with India would be to destroy the aim forever without doubt even if it destroys India. A strike on their industrial districts could mean loss of trillions . So we have a deterrent . In fact one might argue that our deterrent is better against China than against pakistan. Because the Chines would be averse to an economic loss couple of trillion dollars . While Paki's have a suicide mentality in any case even if it means wiping out whatever rudimentary source of income it may have.
China is easy to deter as even 4 Hiroshima size nookes on their main cities will bring unacceptable loss to Chinks, and chinks are pragmatic about war consequences. For TSP, even 100 may not be enough unless KSA is taken down too as it's a suicide nation. Some comments from Yahoo point how to finish the source

I think the President should call Saudi Arabia and tell them that we are starting a new policy----if there are any extremist Muslim terrorist attacks on the USA, we will level one Major Mosque or City in their country of each terrorist captured or killed. You would see the tips pickup and the terrorism grind to a halt. No other way to deal with these crazies.
Just nuke the middle east. It's not our problem.
1998 TN may have been dud but this is 2011. No one doubts Israeli TN capability without any test and in 2011, any enemy that doubts TN capability of India is delusional.
