Sure there may be various ABM defenses, but these defenses will not work if a Palestinian/islamic team smuggles a nuke through a tunnel into one of two major Israeli cities or a fishing boat drops off a team to plant a nuke in Tel Aviv.
Missiles can be detected and hopefully destroyed after launch, however, nukes can be placed in various modes of transportation to their ultimate destination, be it Israel or here.
Bump for further discussion.
What you stated is alarming true. Islamic Terrorist Inc is well aware of the overwhelming retaliatory capabilities directed at state sponsors of jihadism, if they trigger the nuclear unthinkable in Israel, the U.S., the U.K. and other 'targeted' western nations by Muslim death cults.
Although swift, powerful, retaliatory actions could topple the enemy behind the visible enemy, such actions will not bring back the dead victims, nor heal the thousands of injured of jihadists, but removing the only viable natural resource earning billions, crude oil exports, from the blood stained financial hands of Jihad Inc (OPEC) will effectively destroy their current massive spending spree fueling jihad via terror on an international basis, and more important fro the U.S. & global economy, open the doors for domestic drilling & refining in the U.S., drawing ever closer to energy self sufficiency.
