If you claim to be part of anything and presumably if you call yourself “Israeli” you are saying you are part of Israel, then you of course must consider what part you play in the behaviour of the group you are in. Most Israelis take an active part in their country, they pay taxes, do national service, vote, etc etc. if you then use those taxes to buy weapons and oppress, use that military resource to slaughter and oppress, vote in a government that behaves in the way it has been then of course you are accountable, how could you not be?
