Article's not actually useful. The source is primarily from the IISS military balance. I'd rather read the military balance itself rather than this article.
The article makes comparison of numbers. This is actually quite meaningless or misleading in many aspects for example,
(i) One country might have a military half the size of another but 10 times less territory to defend;
(ii) It doesn't take into account deployment, tactics, training, logistics, serviceability etc that all count in a true balance.
Sure, I might have 5 fighters and the opposing has 1. But if 1 is a F22 and 5 are Mig 21s, that's misleading isn't it?
"Balance" is of course used in the context of a weighing scale than the suggestion of parity.
Once you see it in that context, you'd realise how amateurish the article really is.
Just to clarify, I'm not saying that India doesn't have a military advantage over Pakistan. Just that like WAR says, its normally a pointless exercise masked by unrealistic nationalism. Just look at the pakdef forum. Rationality is a scarce commodity there.
