why the afghan war must continue

the wave of bombings in pakistan proves how weak that gov. is. as long as the talaban is fighting a two front war the pakastani government will stand. if pakastan falls than the most hard line religious leaders who preach extreem violence espesaly against the US and Israel will gain control of pakastan's nuclear bombs. the only reasion this hasnt allready happened is because we are spliting the extreemists forces between fighting us and pakastan.
