We can beat India alone, even the Indian Army itself already said "India cannot possibly match China, and the gap is growing larger every day".
We have the high ground on the Tibetan plateau, possibly the best defensive position imaginable.
And New Delhi is only 300 km from the border, we won't even need to leave our own side of the border to hit the Indian capital with conventional artillery, our rocket artillery for example has a range from 350-400 km. And we have the largest manufacturing base on Earth, and more currency reserves than the rest of the world combined, we can build infinite numbers of cheap rockets as long as we need to.
We can just sit on top of the Tibetan plateau and fire on New Delhi, and India has no chance of breaking through against a defending and vastly superior armed forces and vastly superior infrastructure and defence production capabilities.
The only question is whether or not Pakistan will take up our offer this time, to come in after we had already defeated India. Ayub Khan refused, and preferred to side with India back in the 1960's. But times have changed, I do not think they will give up such an opportunity, especially since we will be the ones doing the heavy work.
Anyway, Modi the mass murderer seems to be the perfect vehicle to see another Forward Policy, with his "new assertive posture" on both the borders.
