President Obama and Israeli Prime Minister Benjamin Netanyahu said Wednesday that the U.S.-Israeli relationship is strong as ever, solidified by last week’s unprecedented military cooperation outlined in a memorandum of understanding.

“I don’t think people at large understand the breadth and depth of this cooperation, but I know it; and I want to thank you on behalf of all the people of Israel,” Netanyahu said standing next to Obama before the two sat down for a formal meeting in New York on Wednesday, where both were attending the United Nations General Assembly.
