I disagree that it 'finish them off' is apt because 'finish them off' implies that an entity is weakened and on it's last legs.  If you 'finish off' a beer, for instance, it means that most of the bottle is gone.  That does not seem the case at all with Israel.  They have a well developed and highly effective strategy of parasitizing and subverting powerful nations to work in their interests, and their programs seem to be going strength to strength.  Their increasing propensity toward violent ethnic cleansing reflects this...and Biden's 'win' seems to have given them an extra shot of juice.
