I think that Hezbolla want to keep Israel busy with the rockets so that Israel doesn’t pound the Bat Snot out of Iran and Mock Mouddinnjacket.
Hezbolla, Hamas, and the other factions of the Muslim Brotherhood under-estimate Israeli intelligence and capabilities and determination. They are the best of the best simply because they are fighting for the right to exist.
Think what the USA would do in such a case. Oh, right, we nuked Japan and fire-bombed Germany - good. We can agree we have weak leaders nowadays, but if it was about our survival...things would take a quick turn! I would bet everything I have that the Trident missles would go airborne to protect our children, even with bambi in office. Our nuke subs are the only thing that let me sleep at night while Navy during the cold war, and even now.
Our Trident sailors may not be hard ass grunts (love them), but they are the most highly trained and focused military you will find on this rock. Have you ever imagined what stress they incur every day knowing that they could destroy much of the planet? I've talked to a couple of them in my Navy days and found them to have that 1000 yard stare the grunts have.
Sorry, got off topic.
