Corruption means something legitimate is happening that can be corrupted. Maduro was president of a sovereign country. A bunch of kidnappers and murderers invaded the building he was in in Caracas, murdered everyone in the room, then kidnapped him and his wife. What's the "mission"? To pop up in some room and slaughter everyone in it, then kidnap his wife and him? In order to help steal the resources, billions of dol…
You're apply the oppressor–oppressed framework. Basically Madura and his regime, along with Gaza, West Bank and others are the victims because they're less powerful and therefore above reproach? However US and Israel are currently powerful and therefore they are the only ones worthy of criticism and scorn? Gaza, for instance, is famously anti kidnapping.
Second the west likes to take the moral high ground. That involves holding them to a higher standard.
Third, in cases such as Gaza, and the west bank, they don't have stable governments because of actions by Israel. You can't expect them to behave like a nation state in those circumstances, so yes I do expect more of Israel.
Fwiw I'm British, I remember the troubles on Northern Ireland. I don't condone what the IRA did, but I would still expect my govt to behave better, even though I agree with them.
