The point is, why does a supposedly "growing" economy need to cut it's defence budget?
That sounds like their economy is shrinking, and if you check the IMF data, India's economy really decreased year-on-year due to the constant falling of the Rupee. All of India's stuff is priced in foreign currency since India can only buy overseas weapons, they can't make their own bullets.
There goes the idea that India was actually "growing".
Maybe growing in Rupee terms, but decreasing in terms of nominal GDP with the rest of the world.
