I doubt Belarus needed the Morales thing as a cover.

Yes, this was the casus belli for the war of 1812, supposedly. But the reality in statecraft is that this is rarely the actual reason and there's much more in depth and structural reasons for the start of war.

Yes, indeed, Israel's kidnapping of Adolf Eichmann from Argentina was justified. Snowden is not a Nazi war criminal though, so the comparison only goes so far -- Snowden -at least thus far- is a much more pedestrian sort of criminal than a war criminal. It is possible to feel that the kidnapping of a war criminal abroad is justified and also feel that the kidnapping of a mere spy abroad is not.

Have they mentioned it? Anyways, it's easy propaganda for them, isn't it. Sure, it can't be avoided to give the other side some propaganda wins from time to time.

Not only. It was also the reason that the Marines exist, as they fought a small war in Tripoli over kidnapping of civilians. I'm sure there are many examples. Anyways, my point is just that we can't blanket condemn people who link these two incidents as shills for Lukashenko.
To whom? No-one on this site was instrumental in deciding to hinder Morales's flight, and I doubt many supported the action at the time. It's obnoxious and comes off like trolling for an argument. Dispassionately making the link is one thing, but most of the comments of this form I've seen are borderline tu quoque nationalist trolling.
> Actions of a state against another state's leaders is one thing. Actions against civilian aircraft is another thing entirely.
Wars have been fought over both, attacks on state ships, and attacks on civilian ships. Both are casus belli. Attacks on ships carrying heads of state are particularly problematic absent war, so technically the Morales incident was the worse one, yes (though, of course, if he'd been carrying Snowden then that would in itself have been casus belli), but that does not excuse attacks on civilians.
