I must be mistaken. I am unaware of insurgents flying Mig-21s with more fighter aces and shooting down enemy planes with 2:1 kill ratios? Were the Taliban flying Migs and shooting down planes with SAMs? Please answer, what insurgency is equipped with fighters, SAMs, tanks, etc?
What was the air to air kill ratio in Afghanistan, against an insurgency? What was the air to air kill ratio in Vietnam, supposedly an 'insurgency'?
Please answer for me, very simply: do you see more names affiliated with "North Vietnam" or do you see more names affiliated with "United States" on the list of air to air fighter aces?
I'm also curious, why would the US be scared of invading North Vietnam directly? Surely that would be a conventional war and they'd win a conventional war so why did they choose to allow 'insurgents' to shoot down 10k planes?
