The Ukraine is not usually considered part of the West, and is neither part of the EU or NATO. In any case, there's a pretty clear difference between ordering a plane to return to its point of origin, and diverting a plane travelling between two unrelated destinations under false pretences.
I strongly opposed NATO's behaviour over Snowdon, but this is also not a similar case. Unlike commercial airlines, whose flights are covered by international treaty, state aircraft such as the presidential flight involved, are required to request permission to enter the airspace of countries they fly over. NATO aligned Portugal (where it had planned to refuel) and France refused this permission - as they are entitled to do under international law - and the flight diverted to non-NATO Austria to refuel. Shoddy behaviour, if you ask me, but it does not violate international law and it does not involve abusing processes that protect the safety of aircraft and their passengers and is thus quite unlike the behaviour of Belarus in this case.
I think you're right, but the reality is that international politics is, always has been, and always will be, about power. Countries, or collectives, with power will behave in the ways that benefit them and prioritise this over moral and ethical consistency.
