Israeli Prime Minister Benjamin Netanyahu (2nd L) stands next to Israeli President Reuven Rivlin (3rd L), as he raises the Israeli national flag during a ceremony taken on the Rahav, the fifth submarine in the fleet, after it arrived in Haifa port January 12, 2016. The Dolphin-class submarines, widely believed to be capable of firing nuclear missiles, were manufactured in Germany and sold to Israel at deep discounts as part of Berlin's commitment to shoring up the security of the country set in part as a haven for Jews who survived the Holocaust.REUTERS/Baz Ratner
