How many submarines, B-52's and aircraft carriers did Vietcong have? And they won.
I agree. Miloslaw's comments about Russia's impotence, as supposedly demonstrated in Afghanistan and Chechnya, are laughable.
As an illustration of the many levels of "wrong" in Miloslaw's comment - the Russians were not fighting "drunk Chechens", but rather radical Salafists that were trained in specialist camps in the Middle East, and who would never touch a glass of alcohol. Many of the Chechen insurgents had experience serving in the Soviet Army, while their leadership consisted of former Special Forces operators and an actual soviet general. Regardless, once Russia got serious about the insurgency it handled it within 6 months, at the end of which the UN declared Grozny the most destroyed city in Europe since the fire bombing of Dresden during WW2.
As regards Afghanistan, the ISAF currently relies primarily on military infrastructure erected during the soviet occupation - which by any measure was a more successful occupation than the current one lasting from Oct. 2001 (1 month after the twin tower attacks). When in 1988 the Soviets abanadoned the Afghan government they installed, it managed to defend itself against the Taliban until 1995. When Trump pulls out forces from Afghanistan this year, it's a question whether Ashraf Ghani's government can survive even 6 months without American help.
Long story short - using Afghanistan and Chechnya as examples of Russia's conventional military impotence is foolish.
