It might not look like that, dirty mushroom clouds. Israel has many neutron and EMP nukes for enemy nations, as well as battlefield nukes to take out advancing armies. The neutron and EMP nukes will devastate enemy economies while not overly polluting the planet. The battlefield nukes will stop an enemy from advancing into Israel. The enemy will quickly give up. Maybe a two or three day war, with Israel the victor, a bitter victory with many casualties, but Israel survives.
