We have here some "truths" based on observations made by various people and those truths make a good starting point to build a model and see if all the observations can be made to fit together.
We have the observation that the Pakistan army is the US's whore and the US will do anything to protect that whore. The assumption here is either that whore is doing everything the US wants, or that the whore is generally (if reluctantly) doing enough to keep the paying customer happy. Either way the US needs that whore, and to that extent will protect her against her enemies.
Who are the whore's enemies? Primarily India. But there are some minor enemies - people and groups in Pakistan who are opposed to the whore. The US actually fights the latter directly - using Bredator djinns, or alternatively generously funds and arms the whore to fight them.
As for India - we know that the US has, In the past armed Pakistan to the teeth - making Pakistan almost win in 1965. The main loss of 1965 for Pakistan was the fact that its aims were not achieved, From 1965 to 2010 India has worked to get military (and economic) superiority over Pakistan despite the US. The current "balance of power" between the Pakistan army and India is such that the US can certainly help it give India a "bloody nose" but that is not counting what India can do - i.e to sew up the whore's orifices so the US finds difficult to use the whore.
Let me expand on that. What India can do in a short war is to damage the assets and echandee of the Pakistani army perhaps at the cost of a bloody nose to India (assuming the war does not go nuclear). In other words the US's whore, which the US seeks to protect will be hurt. How will a hurt whore affect the US? So what if the Paki army is hurt? Why should that affect he US?
The Pakistani army is clearly not doing "enough" as per most US accounts. Other acounts say that the Pakistan army has 80,000 or so troops in the region and has brought Waziristan back from the brink - and is doing a marvellous job. If the Paki army is doing nothing, then the US loses nothing if it is damaged. Clearly the Pakistani army must be doing something. Doing enough to be politically useful to the US to tell Americans that "Pakistan is an ally". And the Pakistani army is doing something cheaply (for the US) that the US itself is unable or unwilling to do - probably putting in men in areas where the US won't put them in large numbers
The corollary that follows from this is that is that if the Pakistani army is useful to the US any serious damage that the army experiences will reduce its usefulness. This corollary fits in with the premise we started with i.e "...
the Pakistan army is the US's whore and the US will do anything to protect that whore. "
The whore in turn seeks from the US an ability to keep on fighting India, the ability to keep LeT working and intact. The US of course is not totally dumb. Ideally, from the US's viewpoint anything that keeps its whore happy and working for the US is OK as long as the whore does not work against US interests.
For the US the LeT is both a threat and an opportunity.
The "opportunity" offered by the LeT to the US is the happiness and joy that the whore army gets from keeping its anti-India arm alive and healthy. By allowing that the US is possibly having its work "subsidized"
The threat from the LeT to the US is twofold
- a) The LeT itself can shield anti-US interests in the guise of a "specific anti-India" army. The LeT is an Islamist army ally of the whore and the US is not too popular in Pakistan
- b) If the LeT goes too far - India may be force to hit the whore. The US can bribe the whore - but an India that is pushed enough will hit back, damaging the whore. The US can control the whore, but the US does not control the LeT.
So what can the US do about the LeT that is in "US interests"? They can avoid putting too much pressure on the whore to wind up the LeT. The whore will not wind up the LeT. But at the same time they will have to pressure the whore not to allow the LeT to work against US interests. The US interest is to keep the whore intact. So any anti-US actions by the LeT are out.
What about anti-India actions by the LeT? Now here the US is willing to let some anti India actions occur as long as India is not provoked into war. This offers a very interesting opportunity because the US is playing a double game without direct control on the game.
1) The US has no direct control on the LeT. The US must pressurize the whore to control the LeT
2) The US has no direct way to control India. The US cannot stop India from hitting the whore and a damaged whore is deemed costly for the US
3) India cannot control the LeT or the Pakistani army. But India can threaten the Pakistani army and make the US react to stop that.
These points can pan out into various conflict scenarios. Every conflict scenario is costly to India, the whore and the US. The assumption I am going to make here is that every party will seek to avoid what is most costly. With this kind of balance the "cheapest" option is for a subtle cooperation between the US and India where India promises not to hit the whore if the US can make the whore control the LeT.
We go right back to the question" Does the whore control the LeT?". My belief is yes the LeT is under control of the whore. So a possible future (maybe current) scenario is a behind the scenes cooperation of the US and Pakistan where the LeT is kept intact but pressure is applied on the whore to stop the LeT from doing all that it can
This is clearly an unsatisfactory situation for India, but I think that "winding up the LeT" has no meaning looking at the close links between the whore and the LeT. India may have to play an indirect game of getting the US to keep the whore and LeT under control by being threat to the whore, but without actually carrying out that threat. I haven't put this down in gaming terms but there seems to be some sort of Nash equilibrium here. Need to work on that to see if I can validate that.
Perhaps this explains the uneasy stalemate that we are seeing today. How this stalemate can be upset (if it becomes cheap for any party to upset it) and who might upset it - I will leave for another time. This is already too long.
