>Aren't these wars lost not on tactical side but mainly on political side?
I don't think so, no.
It was just constant wearing down in small tactical victories. Ambush a few vehicles, ambush a few squads, booby trap this, RPG that, shoot down a helicopter.
Maintain casualties on the enemy, while minimizing your own, and eventually the enemy will get tired and go home. The Afghans and Vietnamese became the landscape - they knew where and when to expect the intruders, they applied force in the right places, and withdrew to safety. It didn't always work, but they eventually mastered it. The US and Soviets respectively took enough casualties and the wars dragged on long enough that popular support for the wars eroded.
