I didnt advice the american government since I am not an advisor.
But I am a keen student of history and especially 20th century warfare.
There have been instances where an insurgency has been defeated.
In the Philippines in 1912 or Malaysia in the 1950’s. Both times they had a 10:1 ratio.
Why would the Americans distribute Arms to Afghans then the same Afghans are killing them?
Or Are you saying that the Pakistani taliban is a seperate movement than the Afghan Taliban?
