The United States has indirectly informed Iran , via two European nations, that it would not back an Israeli strike against the country’s nuclear facilities , as long as Tehran refrains from attacking American interests in the Persian Gulf , Yedioth Ahronoth reported Monday.
According to the report, Washington used covert back-channels in Europe to clarify that the US does not intend to back Israel  in a strike that may spark a regional conflict.
In return, Washington reportedly expects Iran to steer clear of strategic American assets in the Persian Gulf, such as military bases and aircraft carriers .
Israeli officials reported an unprecedented low in the two nations’ defense ties , which stems from the Obama administration’s desire to warn Israel against mounting an uncoordinated attack on Iran.
