It is impossible to rely on defense alone, because Israel simply isn’t big enough to absorb the damage when the defensive systems are not 100% effective. More importantly, a strictly defensive posture has zero deterrent ability. Why not fire rockets at Israel if the worst that can happen is that they will get shot down?
The popularity of the rise of chassidus did not go unnoticed by those who did not share the same allegiance. As long as the movement was limited to the commoner and isolated in a few pockets of Poland no one perceived it as a threat. But all of this had changed by 1772.
The fight for Jerusalem continues, on a number of quiet fronts. And if “want of a nail” can lose an entire war, as per Benjamin Franklin’s poem, Yerushalayim can certainly be won via our close attention to issues that may not appear decisive or crucial.
It would be unreasonable for Israel to draw any comfort from an argument that Iranian intentions are effectively harmless. Rather, such intentions could impact capabilities decisively over time. Backed by appropriate nuclear weapons, preemption options must somehow remain open and viable to Israel, augmented, of course, by appropriate and complementary plans for cyber-defense and cyber-warfare.
Summertime in Massachusetts, one often sees flowers for sale at the side of the road. But there is no salesperson present. Instead, there is a sign requesting $10 for the flowers. You leave the $10 bill on the table and go back to your car with flowers in hand. It is an honors system. There is nobody watching to see if you pay only $5 or if you creep back, retrieve your $10 bill and make off with the money and the flowers. Doing that would be a breach of trust.
