I don't understand the downvotes, this comment is quite on point. Both the British and the Soviet ended up fighting in Afghanistan and regretting it. It's an historical fact, regardless of what you think of the US invasion.

However when posting it, I was well aware that the quote is older than that: https://en.wiktionary.org/wiki/never_fight_a_land_war_in_Asi...
And that the Soviets and the British ( https://en.wikipedia.org/wiki/First_Anglo-Afghan_War ) both found this out the hard way.
Apparently that hasn't changed yet.
