With its survival at stake, perhaps it is time for Israel to openly test its nuclear arsenal.
Israel should either demonstrate that it has a sufficient stockpile to simultaneously destroy countries such as Iraq, Iran, Syria, and Saudi Arabia -- or expand its weapons to ensure the price the Arab/Islamic world would pay for nuking Israel would be too high even for such barbarians.
It appears that the threat of massive mutual destruction may have averted a Pakistani-Indian war. It is inevitable that a country like Iran will get nukes. Thus, perhaps Israel must develop sub-based nukes to counter the Iranian threat, and put its cards on the table.
