navin Soviet collapsed because it had bad economy not because it spend more on military it was just that it didnt make more that it can spend!.
India doesn't have to go that way, India can spend upto 3% of GDP for defence (our current is 2.5%), but it can surely spend another 1% of GDP on new technology, reserarch and development, and especially on indegneous production and development. The 1% of Indias GDP is quite high close to 6billion dollar now-a-days and if spent well, we can surely see extradordinary benefits!.
