The Hizballah forces in Lebanon are preparing a Summer Offensive that will change the nature of the world as we know it.
I am concerned that Iran’s pursuit of a nuclear weapon is simply a deliberate provocation to induce an Israeli preemptive strike. That preemptive strike presumably would be launched against military targets rather than major cities. Iran surely would incur many casualties, but nothing on a scale to threaten its survival.
Conversely, the Iranian nuclear retaliation would wipe out at least one or two of Israel’s most populated cities. In conjunction with 40,000 to 80,000 Hezbollah-controlled missiles, chemical weapons and whatever other military capabilities Iran chooses to toss in, Iran at least has a shot at decapitating Israeli leadership which would short-circuit the Samson option. Israel as a nation would be destroyed as the residual population almost certainly could not repel the ground forces that would follow from neighboring enemy states.
In this context, having a submarine-launched nuclear capability that is unequivocally survivable could then carry out elements of the Samson strategy. Whether knowledge of this could ever deter a mad-man such as I’mANutJob is debatable.
