What do you mean "the current war"? This is just the latest episode in a conflict which has been ongoing since the 19th century. If a bunch of European foreigners expel you, take over your home, steal your land, what should you do; welcome them with flowers and a smile and hand over your keys-or fight? Palestinians chose to fight, as did the French resistance under Nazi occupation, as did the brave Poles. Nobody called the French or the Poles 'terrorists', except the invading occupiers. Regardless of what the international community which supports Israel calls them, the Palestinians have the right, under international law of armed conflict, to armed resistance against a belligerent occupier-Israel. See below:
Quote; "Members of the [occupied] territory's armed forces who have not surrendered, organised resistance movements and genuine national liberation movements, may resist the occupier".
