Sanctions against Iran should be given a chance, but at some point other options must be examine Israel’s Defense Minister Ehud Barak said in an interview prior to his departure for Washington.
 

While the U.S. and Israel share the same belief that Iran is determined to reach nuclear capability there are differences between the two countries on what should be done and the time frame in which certain steps should be taken, he told The Washington Post.

Israel’s defense chief also warned that in the event of violence erupting along its northern border with southern Lebanon, Israel will strike at the Lebanese government which is allowing Hezbollah to rearm. Since the end of the Second Lebanon War in 2006, in violation of U.N. Security Council resolution 1701, Hezbollah has built an arsenal of over 40, 000 missiles and rockets, Israeli officials have said.
 

Barak told the newspaper if Hezbollah fires a rocket into Tel Aviv, "we will not run after each Hezbollah terrorist or launcher. . . . We will see it as legitimate to hit any target that belongs to the Lebanese state, not just to Hezbollah."
 

Tensions between Israel and Lebanon have escalated in recent days amid reports that Lebanese activists plan to dispatch aid ships to the Gaza Strip in violation of an Israeli blockade. Barak called the aid ships an "unnecessary provocation."
 

Barak is due to arrive in Washington Monday for meetings on regional issues, including progress made on the Israel Palestinian peace tract, the Iranian nuclear threat and security issues concerning both countries.
