It is indeed. I'm not sure that the US ever apologised properly for
Iran Air Flight 655, or the Soviet Union for
Korean Air Lines Flight 007
What is this obsession people have with formal apologies, and what constitutes a proper apology? None of these incidents have had apologies, so far, but one of the three has resulted in financial reparations/compensation for the families of those killed. Perhaps Russia will make reparations for this one, unlike the previous one.
I've never seen an apology for invading another country and massacring the inhabitants.
Except for Japan, you possibly never will. Not from Germany, the US, UK, Russia, Iran, Israel etc. etc. War is always dirty, is not a playground fight, and apologies never mean anything, especially without accountabilityand reparations, and change nothing.
