You are comparing a Half hearted British "Try" with a Full fledged well funded and well equipped invasion by a Super power...
Also you are forgetting the Diplomatic efforts Pakistan did to save Afghans,,or throwing a few 20 megton Nukes to show Afghans their real place,and turn afghanistan into molten glass wasn't difficult for USSR
daisy cutters were good enough to make the brave Talib@stards f@rt in their shalwars.
No I am not gloating at the misery of Talbinis.
Just pointing out the change and updates in the modern warfare.
Afghanistan has specific geography that provides natural resistance to large scale invasion.
However the same geography doesn't provide much cover to the air-attacks and surgical strikes by air-cavalry (a concept used in Afghanistan only from 1985 onwards).
I am an ardent student of insurgencies.
And Afghanistan is terrible country to run an insurgency in 2013.
because the terrain doesn't offer much to provide safe houses.
If Pakistani areas were off limits to Talb@stards, Afghan insurgency would have died in 3 months.
However Pakistan has paid enormous price in men and material.
Our losses are very similar to the losses of NATO troops,
And that's only because Pakistani nation is unwilling to see the downside of supporting Afghan insurgency.
Bottom line.
Pak-one doesn't know or realize that "Afghan aka graveyard of empires" is an obsolete concept very similar to the use of bow and arrow in 2013 warfare.
