Don't agree.
You can't fight a proxy war elsewhere without conventional deterrence.
We fight proxy in Kashmir. If we didn't have the conventional (and strategic) deterrence, India would have simply attacked us directly and shut down our proxies.
Conventional and strategic "numbers" are prerequisites to proxy capability.
I exactly wonder this... how come US was never bothered with presence of Pakistani and Afghani (foreign) militants in Iraq and Syria and God knows where else.
There are all sort of official US reports, but those are just treated as piece of record, no serious persuasion was ever made to address the issue.
Reminds of how US was totally non-serious about Al-Qaeeda network in Afghanistan, in late 90's in-spite Pakistan tried hard to persuade US to do something about AQ, and even offered to hand over OBL. (search for interviews of ISI chief in late 90's Zia ud din Butt), now i'm looking it from same dimension.
On the other hand, i'm suspicious of Imran Khan's trips to Iran, where he behaved quite suspicious, starting from changing the scheduled date of his visit and non-diplomatic activities, incl. meeting general Sulemani (later target killed).. right?
One more thing, the military person in picture from OP is reportedly replacing the Sulemani and is reportedly was operational incharge of mafiaism in Pakistan and Afghanistan, no wonder he was co-operating with Indians and all the most wanted of Pakistan.
A militia that is recruited by a foreign government is a serious threat. Would Iran like the idea of Pakistan recruiting Iranians into a military unit for future use? I don't think so.
That's the bottom line and a fact, most of the rest is baseless and biased theories.
What matters is Pakistan's so called democratic regime, and their tilt, simply put.
The thing is not all Sunnis support Daesh infact it must be even less than 1 percent but supporters of Sunni child killers in Iraq and Syria has 100 percent support from Shias. So no, we are not on the same page.
These people are definitely not normal and in best case scenario normal and civilized people should leave Pakistan, because these baby killers are quite influential in naya Pakistan.
Imagine a dooms day scenario, when same mafia will have both PM house and Presidency in their fist.
They will decide, which lt. is promoted to Captain and which Captain is promoted as Major and so on.... until the General rank and what follows is every one's imagination!
