You said it yourself , what do I want to hear doesn't matter now ... You spent time writing a whole paragraph how Iron Dome system can be easily overwhelmed with low cost artillery shells ...
Right! Far easier to intercept a modern missile than some home made obsolete rockets ... Of course speed and modern technology doesn't make any difference
Wonderful logic !
Pakistan doesn't require that much resources to accomplish the task as you suppose it to be , thousands of artillery shells will be fired from both side , you can assume 50 % successful intercept probability but it hardly matters in the game of thousands - not to mention the extremely cost when compared with low cost artillery shells ... Pakistan army will have to use its artillery for defence just because the adversary possesses Iron Dome ?
Give me a break !
