"The dangers of brinkmanship as a political or diplomatic tool can be understood as a slippery slope: In order for brinkmanship to be effective, the threats used are continuously escalated. However, a threat is not worth anything unless it is credible; at some point, the aggressive party may have to back up its claim to prove its commitment to action."
Israel stations nuclear missile subs off Iran
Three German-built Israeli submarines equipped with nuclear cruise missiles are to be deployed in the Gulf near the Iranian coastline.
The first has been sent in response to Israeli fears that ballistic missiles developed by Iran, Syria and Hezbollah, a political and military organisation in Lebanon, could hit sites in Israel, including air bases and missile launchers.
The submarines of Flotilla 7 — Dolphin, Tekuma and Leviathan — have visited the Gulf before. But the decision has now been taken to ensure a permanent presence of at least one of the vessels.
The flotilla’s commander, identified only as “Colonel O”, told an Israeli newspaper: “We are an underwater assault force. We’re operating deep and far, very far, from our borders.”
