@Narf Germany also lost the war. Should they won it, or at least allied to another super power that came out of it OK, I am sure they will come up with some excuses for the Poland invasion.
Khmer Rouge, after provoking the Vietnamese with cross-border, civilian-killing attacks, lost its capital to Vietnam in 1979. This genocidal gov still got the backing from China and the US to retain its seat in the United Nation up until 1993. And of course they demanded their capital (along with most of their territory) back at every fucking chance they got, and the Vietnamese were always the bad guys.
So you see, if one is shameless enough, one can still twist and turn whatever one's action spoke.
