Prime Minister Benjamin Netanyahu reiterated on Sunday that Iran was the most dangerous threat in the world, saying that Israel was ready to act against Tehran and not just its “proxies” in Syria. Saying he had "a message to the tyrants of Tehran" during a speech at the Munich Security Conference, he warned: "Do not test Israels resolve." “Israel will not allow the regime to put a noose of terror around our neck.” He brandished a rectangular piece of dark green metal which he called "a piece of that Iranian drone, or whats left of it, after we shot it down." Calling Irans Foreign Minister Mohammad Javad Zarif the "smooth-talking mouthpiece of Irans regime," Netanyahu said: "Mr. Zarif, do you recognize this? You should, its yours." Israel has said it shot down the drone on February 10 after it entered the country from Syria, and responded with a raid on what it said was the Iranian control systems for the craft in Syria. During the strikes, one of Israels F-16 fighter jets was shot down, believed to be the first loss of an Israeli plane in combat since 1982. Israels response marked the first time it publicly acknowledged hitting Iranian targets in Syria since the 2011 start of the war there. Again referring to Zarif, who is expected to speak later in Munich, Netanyahu said: "No doubt Mr. Zarif will brazenly deny Irans involvement in Syria." "He lies with eloquence." The Israeli military has claimed the drone was a copy of a US model captured by Iran in 2011, based on an analysis of the drones debris. Addressing the Munich event for the first time, Netanyahu urged gathered US and European officials and diplomats to counter Iran immediately, displaying a map showing what he said was Iran’s growing presence in the Middle East. He said Iran was increasing its power as the US-led coalition against ISIS in Iraq and Syria regains territory from the terrorists. “The unfortunate thing is that as ISIS compresses and Iran moves in, it is trying to establish this continuous empire surrounding the Middle East from the south in Yemen but also trying to create a land bridge from Iran to Iraq, Syria, Lebanon and Gaza,” Netanyahu said. “This is a very dangerous development for our region.”
