India has 29 air bases against Pakistan as compared to about 6 odd against China. Though against China, IAF infrastructure is being improved in order to accommodate new inductions, no major additional airbase(s) has been announced as yet. Which means that against China only limited number of such aircraft squadrons can be accommodated and it is Pakistan where they have sufficient available space to induct additional aircraft squadrons.
This is because of their defence strategy against a two-front war environment, wherein India plays a deterring defence against Pakistan and dissuasive defence against China, though China has been declared as their number one enemy. Such a strategy does have an inherent disadvantage with regard to Indian response against China - they can not place more than what they can accommodate against China.
China has been "declared" the number one enemy not BECAUSE they are the number one enemy, but because they are a good reason to cite in order to increase military spending. It does not actually indicate that India is worried about a Chinese attack as much as it is worried about an attack by Pakistan or by Pakistan backed insurgents/mercenaries.
India' strategy for defence has always been one of deterrence. India will never initiate an attack either against Pakistan or against China. However when it comes to China, the probability of a Chinese attack on Indian borders, is miniscule. The 1962 attack was one of retaliation in response to Nehru's forward policy, and since then China has had 3 opportunities to attack, one even backed by the United States AT A TIME WHEN INDIA WAS MOST VULNERABLE AND AT A TIME INDIA WAS INVOLVED IN A 2 FRONT WAR. The fact that they did not, and the fact that not a single shot has been fired across the borders for 45 years, eliminates any undue necessity for panic.
However, Pakistan is considered "unstable" in this regard. We can never be sure when Pakistan will initiate an attack, and we have had this experience 3 times since independence. Also as sancho said a lot of these airbases serve both purposes, to protect the west as well as the east.
You see this where your strategic thinking is at odds within the three services and with the geopolitical environment that prevail and is emerging. This also highlights the lack of strategic thought and space given therein. Whereas Indian navy talks big about being the dominant force in Indian Ocean, Indian army talks about naxalites and problems in Nepal and Sri Lanka and Maldives and Bangladesh etc etc. The thinking between the two major elements of Indian defence forces are out of sync and if these are out of sync how are they going to maintain the power projection India so vociferously talks about.
Nahin yaar, you didn't ruin it. Why should I be angry with you.
Yes, lesson learned, and moved much ahead than being perceived.
Naxalites and problems in neighboring areas HAVE to be taken up by the Indian Army. I am sure you understand that the naxalite problem cannot be tackled by the Indian navy, as it is not even their turf. The Indian Army is tasked with protecting the homeland and as such they have every right to talk about every problem that they perceive. However this doesnt even mean anything when it comes to war between nations. It doesnt undermine the coordination that exists between the 3 branches of the armed forces. Traditionally this has been Pakistan's weak point in just about every war they have fought. There has been a lack of coordination and communication, not just because of lack of infrastructure but because of the internal power politics at play in the Pakistani armed forces leadership. You say, the lessons have been learnt and that you have moved on, but how much you have moved on remains to be seen. Till about a decade back, you hadn't moved anywhere, so I dont foresee Pakistan being able to conduct a coordinated attack against India, with all 3 branches of the armed forces acting in sync. However I wouldnt underestimate Pakistan. But this isnt something India suffers from. Therefore the Indian Army talking about domestic issues in no way undermines the coordination that actually exists between the 3 branches. Its every much the Indian Army's right to talk about these things, and they should.You draw extraordinary and baseless conclusions from this, I mean your argument doesnt even follow.
As for the power projection, am not sure what you are talking about, because India rarely, if ever projects any power or even talks about it. This I think is both a blessing and a curse. On the one hand India comes across as a soft power, and on the other hand, India keeps a low profile while gaining more and more international credibility.
Yeah, the five odd bases in Indian Occupied Kashmir may be able to look after the Chinese side, but would their division of assets be able to look after both sides - a rather difficult proposition as these bases can accommodate only a specific number of aircraft.
However, it is NE India where the main Chinese interest lies, and here IAF bases in the west can not support directly.
While assessing threat, various contingencies are prepared. Within the India Pakistan China tri-lateral imbroglio, a variety of contingencies can be prepared. Some of these may be:
A war with only China.
A war with only Pakistan.
A war on both Pakistani and Chinese fronts.
There can be many other variables which could be brought in. Each of these have their own set of circumstances which can unfold and create a varied set of environments which may have different responses on offer.
A war with China, and Pakistan only mobilizes but does not interfere.
A war with Pakistan, and China only mobilizes but does not interfere.
Each of the above would require a different set of responses. Which would have a direct and indirect effect on the war.
The thing is there wont be a 2 front war. There is negligible probability that China will attack at a time when its economy is booming and its political credibility in the world is just starting to increase. In case of a war between Pakistan and India, a Chinese deployment on the Indian borders can very well provoke the United States to mobilize on its eastern front. Am sure China wouldnt want that, and therefore they will refrain from any sort of hostile actions. Also China historically has always only looked out for itself and its well being, and as such wont interfere, as has been proved 3 times before, as I have already stated. They will however support you through materially and morally. This is of no consequence to India as Pakistan does not have that much of purchasing power anyway. So all of those possibilities you listed, about China mobilizing or attacking India is mere conjecture and fluff at this point.
As for the nuclear option. India has a no first use policy. Given the fact that neither Pakistan nor China has the capability to actually Invade India, this option is ruled out. India on the other hand wont ever initiate an attack, either against Pakistan or China, so Pakistani or Chinese usage of such weapons is also ruled out. China will not attack, and therefore our usage of nukes against them is also ruled out. In short there wont be any nuclear war between all 3 countries for the foreseeable future. Nor will those thresholds ever be crossed.
