Well, I do think that it is also the USA's concern, if Iran is after Israel. You see, Israel provides the USA with much intelligence and with ingenious tehnological innovations so that the USA can be a progressive superpower in the world. Furthermore Israel's purchases of US -made arms keeps many American workers in the bacon. Workplaces and domestic workforce are vital to the US-economy at this economic crisis, she's in, bc the US unemployment rate is 22% and 16% of the Americans are living under the poverty line. So yes, Israel 'ld be a VIP-ally to the USA, bc she contributes a lot to the US-economy and to know-how and to maintaining workplaces. Where 'd the USA be, if there was no Israel? Defending Israel against the Iranian threat keeps the USA afloat. The USA simply cannot afford losing Israel......mankind cannot afford losing the Jewish nation, for its inventions have advanced its well-being considerably.
