We know this
That's why we shouldn't really give a crap about the west or anyone else
The problem is the Afghans just don't learn, after the defeat of the U.S, they could have lived in peace and had trade and free movement of people
Instead they CHOSE conflict with Pakistan and sending TTP fighters to attack Pakistan
What can you do except fight back?
I think by now we are all experienced regarding warfare´s as we have seen so many of them thru out the last few years and people never seem to learn somehow.
Getting trapped in wars is very real and hard to get out of it. Which is something combatants ignore especially the stronger more aggressive side mostly comes in with delusions of grandeur and gets trapped we have seen this play out again and again.
To you give you an example
Soviet-Afghan war (10 years)
Vietnam-US war 19 (years)
Iran-Iraq war (8 years)
US-Afghan (20)
Syrian rebels vs SAA-Russia-Iran and Militias (14 years)
Russo-Ukraine ( 4 years and counting will reach +10 years)
Heck Israel was fighting for a whole 2 years inside a very small enclave smaller then one district in Islamabad.
The nations behind all these wars were the stronger more aggressive one and they all regret ever waging these wars and if they had a time machine they would have refrained from it except Russia because they are still 4 years in but by the time they are 15 years in it could be different.
Mike Tyson once said everyone has a plan until they get punched in the face and surely wars start this way where someone is in delusions of grandeur thinkin ´´I am going to subdue the enemy etc etc´´ or ´´I am going to cease this amount of land from the enemy etc etc´´ This is what opens the pandora box and sets the trap. The other-side will think holyshxt they wanna wipe us out from the earth hence the push back kicks in between people fighting for their existence and someone trying to subdue others etc etc. escalation leads to escalation and finally both side will find themselves trapped where days will turn to weeks and weeks to months and months to years and years to decades.
Honestly speaking I am not talking about who will get the upper hand here because all of that is irrelevant now if both sides enter a war which will be a very prolonged war that will be fought both in Afghanistan and Pakistan as the pathans in KPK will eventually fight Pakistan itself we talking about like 2-3 decades time of war if not longer hence looking for kills here and there and small gains here and there is entirely irrelevant now.
Besides The only losers in this incident are none other then both countries and especially the one that has more to lose. If the war becomes a reality it will turn into a prolonged war 100%. I think once the war continues for years and an effective civil war takes hold in Pakistan itself, Pakistan will denuclearize by itself and handover the nukes to Washtington which will open the route for India to cease the eastern front.
India will be in this war like a crocodile patiently waiting for a Zebra, Thompson Gazelle or even a Wildabeast to somehow enter the river, this will be India´s moment to move when they see Pakistan exahaust their resources entirely for they know fully well that if this thing takes off it will continue thru out the 20s, 30s and into the 40s.
Hence one most never fall into the temptions of stragetic flaws and mistakes that easily.
