"The people being invaded need to behave better" is one way people justify brutality against Palestinians in Gaza and the West Bank. And despite the argument working better on Hamas, I reject it there too.
In both situations, the chaos is being caused by the invading country, and the onus is on the invader to leave.
You said "LOL" about Ukraine not getting to join the EU, but that was the same attitude the US and Israel had towards UNESCO for daring to admit Palestine as a member state in 2011.
