what would happen if Israel launched surprise raids on suspected Iranian Nuclear weapons sites and Iran replied with Scud missiles tipped with Nerve gas or mustard gas, and it ended up killing say 500+ jews before they got their gas masks on, how would israel counter strike?
would it go nuclear? or would the great USA keep israel restrained? because the US wouldnt want world oil prices to go to $200+/bbl in a full blown arab/iranian/israeli war.
