From those emigrated to US and Canada I know personally
Don't let them drag you into that idiotic discussion. It's irrelevant who migrates where.
The relevant facts are if Belarus had the legal authority over its airspace. That's one way.
The other way is if Belarus operated in a gray zone - legally and morally - by diverting that plane off its original course. This, in comparison to other events, is a slamdunk for Belarus. For starters, you can ask under what rule did Poland have the right to send its military to Iraq. I would like to hear that bs.
If they give you some static about the WMD, ask them to account for the millions who died in Korea and Vietnam. For the extra fun, why is the US still in Cuba.
Perspective is an amazing thing...
