USA and Europe are just trying to keep alive their dying influence in the region -
1. If USA and NATO wants, it can finish off this Taliban business very quickly. But they won't.
2. Pakistan is not allowing US investments into its economy the way americans want it. This will allow USA to take control of Pakistan in more comprehensive way. This is a major contention between US and Pakistan, OBL is only a smaller drama and irrelevant here.
3. USA wants to cut off Pakistan from India and sabotage SAARC economic block. SAARC currency will single handedly over-shadow Euro as single biggest currency block in just 10 years, if you look at market size of SAARC.
4. Keeping TTP alive helps in accomplishing 2 and 3.
5. After the Civilian Govt. (zardari) came to power, 2 and 3 are becoming more difficult because Civilian politicos of Pakistan are in favour of good economic relations with India.
6. The recent OBL episode took place due to event 5. Otherwise, there was no hurry to do 5. OBL episode is convincing me that, USA will attempt something more desperate in coming months to take control in the region.
Now, some obervations:
1. Let it be clear, that an unstable Pakistan in hands of Jihadis is bad for India and China both. But it fully achieves USA+British European agendas for region.
2. There might be some temptations in China to let this unstable situation carry on for few more years or a decade, to slow down regional growth. It will help China push up its own profile in Asia.
3. China has no stakes in SAARC or rupee block. In fact, it will only hurt China(renmibi) as competitor. Same is true with Dollar and Euro. Noone likes a new competitor.
4. Saudis have no role in this region and never had in history. Those who think they have, are fooling themself and only helping outside agendas. Saudis have sold out their own state to west, why they will fight for you? The recent attack on Saudi diplomat was showing this frustration of a segment in Pakistan who believed in that idea. Its a wake up sign.
Points 3,3 above are very important. That's the reason China, USA and Europe all have common objective here. They will keep region boiling forever and break it if possible.
I think the end-game here is, India and Pakistan should join hands to finish off this western funded terrorism mess(started with Saudi+USA funded Jehad war on Soviets) and form an economic union. Lets bring peace and prosperity for our brothers. Its time to complete what was left in 1947.
