Everyone who invades Afghanistan loses - the only winning move is not to play.

And a naval engagement to the Czech Foreign Legion :) Russia has historically been very good at killing off invading armies through attrition, but that's not necessarily a strength when they're the invading army in similarly inhospitable conditions

Russia didn't lose to Afghanistan, rather Russia, Ukraine and Belarus dismantled the Soviet era occupation force. In fact the pro-Soviet government of Afghanistan lasted 3 more years on its own - unlike the US installed government which collapsed before US troops left.

So, Russia, Ukraine and Belurus lost to Afghanistan.

That's not true. The last Soviet soldier has left Afghanistan way before the USSR disintegrated.

They didn't lose to Finland, they forced them to sign a treaty whereby Finland gave up territory.

Finland fought exceptionally well, which shocked the world, but they still lost the winter war.

they use winter like a nuclear deterrent. It’s as good as having an ocean.
