Because Ukraine is not committing brutal crimes, not lobbing rockets randomly, hoping to kill anyone, civilian or not. Not hoping to eradicate their enemy (that is the stated goal of Hamas). Ukraine government is not in power because of violence, but because they were voted in. Hamas is in power only because they have weapons and other palestinians don’t (given to them by other extremist Muslims, who want to see Jews die).
So let me say it again, this conflict is not fucking comparable.
