It's not a full blown war, Pakistan is conducting punishment strikes and targeted attacks against assets and bases that have been used against Pakistan
The Taliban are not capable of fighting a war, not against Pakistan especially
They are a guerilla fighting force
the Taliban does not have the money to sustain attack
It doesn't have the fuel and sending forces to the border burns through Afghanistans meagre fuel resources
The Taliban has limited weaponry and it's needed against it's enemies like Isis,
So sending it to the border for Pakistan to blow it up gives Afghanistan nothing
Winter is coming and even a few days conflict or border closures will hurt Afghanistan
Afghanistan Could collapse if this conflict goes on because they don't have the resources to wage a conflict, neither do they have support
THATS THE POINT
Pakistan has had enough of Afghan stupidity,
They have a choice Trade and peace
Or conflict and being hit
We want the BLA and TTP either destroyed or controlled
Is this the end of it, of course not, the Afghans are donkeys
But we have set the stage now and any attack on Pakistan will result in strikes against our enemies
