OK. One of you gentlemen is already banned, but I'll address the concerns for posterity. Also, you guys are making overlapping statements so to save time I'll give a general answer. If you have specific points after that, feel free to raise them.
1. About Nasr etc. The 'four layer' shield is giving you a false sense of security. Each component of that shield has different capabilities in terms of the velocity and range at which it can intercept. So, for example, you won't be employing S-300 to counter Nasr. So given a certain missile, Pakistan knows exactly which systems can counter it, and how to circumvent that. For example, through a saturation attack. Also, India is a big country. Yes, you have all those radars, but your entire country is not protected by a four layer network. You aren't the 'impregnable fortress' that you believe you are. If you really wanted to make all of India from Laddakh to Andaman Islands an 'impregnable fortress', you will bankrupt your entire nation, notwithstanding the 'trillion dollar' economy.
2. About 'upgraded xyz fighter'. Understand that most of you fighters are for point defence. When you send them for offense, they get shot down. They get show down, by shoulder fired missiles. This is important to understand. Majority of your fighters can be tracked from the ground and shot down by either shoulder fired or larger SAMs.
3. You are the invading airforce, invading a country that is very well defended. Pakistan's smaller size means it is also very easy to cover with our defensive systems. Imagine this, soon we will have 9 AWACS. India is approx. 4 times larger. Do you have 36 state of the art AWACS? Similarly, the coverage of our air defence systems is denser because of smaller area.
4. From an offensive point of view, your best bet currently is M2K and Tejas/Rafale when and if you acquire them in sufficient quantities. As I explained already, regardless of the ECM capabilities of Su-30 MKI, it is a lighthouse in the air. You shouldn't really brag about it.
And so now you see we are in a very good position relative to India for defending our borders. Alhamdolillah.
