Who is a responsible nation ? What right Us had to bombard Iraq just on the pretext of WMD, which they never found ? If Iraq really had WMd or Nuclear weapons do you think Us would have dared to invade them ?. So, we need nuclear deterrants, becuase we are living next to roughes like Pakistan, and over ambitious China, who have already eaten big terrotories of India and still claiming Arunachanl Pradesh.. Our Singh is loosing sleep over athe arrest of some terror suspect, he does not have time to think of nation's security..
