What would happen if a 1-megaton hydrogen bomb exploded over the Azrieli Center in Tel Aviv?

(Based on conclusions drawn by the US Army from tests conducted with hydrogen bombs)

Within a radius of 4 km of the explosion (the inner circle), everything evaporates and turns to atoms.
Within a radius of 6 km of the explosion (the second circle), every structure above ground is destroyed.
Within a radius of 10 km of the explosion (the large circle), everything burns.

The heat generated by the explosion of a hydrogen bomb exceeds a million degrees Celsius. Carcinogenic radiation remains across the whole blast area for many years. Because Israel is small and most of its population is concentrated on the coastal plain, two hydrogen bombs - one on Tel Aviv and one on Haifa - are enough to destroy Israel. No damage Israel might inflict in retaliation would repair the damage to Israel.

Israel's nuclear weapon was meant to deter, but it has become the accelerator of the nuclear arms race across the entire region. Only the disarmament of the entire Middle East from all nuclear weapons - under international inspection - will prevent a nuclear holocaust.
