What Israel does not know

"Later on in the conversation, Levite told the Americans that Iran could obtain nuclear weapons within two to three years, but admitted the estimate could be inaccurate as "Israel does not have a clear or precise understanding of Iran's clandestine program."  Without citing any sources, Levite noted that there are rumors that Iran has already obtained "some warheads from Ukraine," the telegram added. He claimed that, "Israel knows that Iran has acquired cruise missiles from Ukraine."" (thanks Heidi)
