Veitnam was a war lost for the US. reason simple the Viet cong were supplied warfare against russia by the US, which was used on then later by the extremist Vietcong. Same happend in Afgan It was the US weponary which killed their soldiers in afganistan. Pakistan have enough problem of their own to look at us as veitnam or any thing. Its we the people who bring such people to the fore that they start ruling us.
