What makes you think Israel doesn't have global support as a sovereign nation? And since when did "the international community" consider pro-Russian Ukraine separatists as legitimate rebel forces?
And what part about those Palestinian *civilians* being killed, caught in the middle between no-state status, minority Hamas factions, and Israeli defense measures doesn't matter? Long, slow, drawn-out ethnic killings don't count as "massacres" unless it involves Jews? Please, tell me I read your post wrong.
