The man is a liar and cannot be trusted. If Singh has any sense, he would avoid making deals with such a scoundrel.
Okay to deal, but either cheat or be cheated. One should always understand this when dealing with cons like Musharraf. (Vajpayee learned this the hard way.)
An aside: I remember reading of the condition of certain Jawans' bodies during Kargil. Musharraf is a Suited barbarian, but clever. We will regret ever calling him anything else.
