If the average wind direction blows from Gaza to Israel, so would nuclear fallout. If it’s nukes, it would make more sense to detonate downwind - say, east of Israel - say, in the direction of historic Babylon ... say ... Ezekiel 13:19-20
Very little fallout if exploded at correct altitude. Airburst with “clean” nuke is very feasible.
I meant Isaiah 13:19-20
