I just want to say that from today please don't make fun of Indian failures. We don't deserve it. It is not fair because India tries new things and fails, Pakistan never dares to enter high tech fields, so it is succeding since independence.
Now the important lesson:
I am sure Pakistani engineers today are watching India. The reason why India is so ahead in this field is that we have patience. Patience is the ultimate success secret.
Don't be so cocky!
And don't forget that India lags Pakistan in missile development as recently reported by the Bulletin of Atomic Scientists.
The most authoritative non-governmental assessment of world nuclear forces has revealed that India's nuclear capabilities are seriously lagging behind those of its putative adversaries, Pakistan and China. The evaluation by Hans M. Kristensen and Robert S. Norris in the Bulletin of Atomic Scientists called "Indian nuclear forces, 2012", reveals that for New Delhi, the principal means of weapons delivery remains fixed-wing aircraft like the Mirage-2000 and the Jaguar. Unlike Pakistan and China which have substantial deployed missile arsenals, India's missile force is lagging, despite the test-launch of the Agni V in 2012. As the Bulletin notes, "the Agni I and Agni II , despite being declared operational, both have reliability issues that have delayed their full operational service".
India's nuclear arsenal failed by 'unreliable' missiles
It confirms that Pakistan possesses advanced rocket technology. Pak can deploy it for space launches if it so chooses and quickly close the gap with India in the space race.
