well congrats to Pakistan, but we have many things ahead to take care of. Cryogenic engines, our space program, and satellite technologies. we already posses Agni 3 and developing our own ABM technology. what more infact we also don't know. You know its always a secret.
yes we have failures but they are just temporary, because its always something new, failure right now is no problem we can rectify for war time.
we can develop a really sophisticated missiles carrying Mega Tonne bombs but the problem with us is we do not mix our space programs and defense programs together to avoid sanctions.
