There is no evidence that Bibi has any intention on attacking Iran. We have spent so long with pointless diplomacy going round and round in circles for so long now that Iran has been able not just to enrich uranium but to modernise its air defenses and so with the hardware Israel has its unlikely that it would be able to do anything and its only the US now with their stealth aircraft, and heavy bombers launched from carrier fleets in the Gulf and their base in Bahrain that can do it. Right now Israel is hoping to slow things down through computer viruses like Stuxnet and assassinating Iranian nuclear scientists to try and buy more time until a solution can be found. If Israel does have the capability then the smart thing would be to hit Iran because its better to go to war today to destroy the Iranian nuclear program rather than risk the fact we may go to war one day in future and be facing a nuclear Iran. At the end of the day though there is ZERO evidence Bibi has any plans to attack Iran and this entire article is based on speculation.
