Netanyahu, IDF high command tout new German-made submarine
The arrival in Haifa of Israels newest submarine, the INS Rahav, sends a message of deterrence to Israels enemies and of strength and security to Israels citizens, Prime Minister Benjamin Netanyahu said Tuesday, hinting at a possible Israeli second strike capability.
Our submarine fleet will act as a deterrent to our enemies who want to destroy us.
They will not achieve their aim. They need to know that Israel is capable of striking with very great strength at all those who would harm it, he said, noting the submarines may be able to respond to a nuclear attack on Israel.
According to foreign reports, Israels submarines are armed with nuclear missiles.
Netanyahu added, And the citizens of Israel need to know that Israel is a very strong country.
