Sometimes quotes get mistranslated and the only people that catch it are the ones for whom Arabic is their mother tongue. AFAIK the Palestinian Arabic dialect has some differences with what journalists at Al Jazeera might be used to.
Maybe it is a similar but different thing for Deif.
Israel has occupied The Gaza strip for decades while Russia is invading Ukraine. Is kind of discounted by the occupation of Crimea but since that is in contest right now, maybe that's not so much an occupation anymore but a war.
You're definitely from reddit if your being pedantic about what a military Commander is saying to rally his cause. "Actshually there are other occupations going on".
Also are you really trying to make this about Ukraine??
