Nothing good to show, plenty of evil planted in those poor regions (Afghanistan, Iraq) which will be fucked for many generations to come. And if having a better trained military makes it justifiable for somebody I dare to ask what kind of human being is he/she.

Ukraine is so far another story but nobody has clue how it will evolve. And none of that military experience is getting to any actual use and is slowly evaporating, its so far just about minor logistics, some satellite espionage and some troops training (which are not negligible skills but they alone don't win wars).
