It was painful reading Prime Minister's comments that Pakistan can't wage a war with US and that we will try to resolve the issue of US attacks on our soil through diplomacy. This came a day after the bold comments made by COAS regarding safeguarding Pakistan's sovereignty at all costs. One fails to understand why our leaders show such cowardly attitude when the whole nation, and our armed forces, are standing right behind them to protect our soil from foreign aggression. What are they afraid of? It is also very interesting to note that Iran, a country way behind us in terms of military capabilities, has repeatedly told off US many a time. When will our leaders learn to live a life of self-respect and dignity instead of taking refuge behind the cowardly 'diplomatic' negotiations? -DR IRFAN ZAFAR, Islamabad, via e-mail, September 17.
