US President  Barack Obama’s first engagement upon landing in Israel on March 20 will be a quick tour of the Iron Dome missile interceptor stationed at Ben Gurion international airport. After a round of handshakes, the officers and men operating the system will explain how it works.

The innovative counter-missile weapon is to be deployed there, not just as a spectacle to honor the US president for his contribution to its development, but out of necessity for his safety. Air Force One might be seen as fair game for the ground-to-ground missiles wielded by Al Qaeda units fighting Assad in Syria and its affiliates in the Sinai Peninsula at the very moment that the US President steps down to the strains of the IDF welcoming band.

 In normal circumstances, personal security arrangements for a US presidential foreign visit are kept under close wraps and rarely visible to the public.

This time, debkafile’s counterterrorism sources report, the visit’s planners made an exception. They decided there was no option but to visibly install an Iron Dome battery inside the airport, because the first battery plus a Patriot interceptor stationed for more than two months north and south of Tel Aviv were not sufficient guarantee of security against rocket attack for President Obama’s arrival.

This decision set up two precedents:
1. Air Force One will land on the Ben Gurion airport runway on March 20 enclosed by two defensive rings of US and Israeli missile interceptors in the densest formation ever to guard an American president's arrival in Israel.

2. The Iron Dome battery will stay in place for the three days of Obama’s visits to Israel and Jordan. It will defend Jerusalem’s air space against rocket attack for the duration of his stay.

Still fresh in Israeli memories are Hamas attempts just five months ago to hit the airport and Jerusalem with rockets fired from the Gaza Strip on the orders of the Iranian general Gen. Hassan Shateri aka Hossam Khosh-Nevis. This Iranian officer was killed in January in Syria in unknown circumstances.

No one in US and Israeli security circles is seriously suggesting that Iranian leader Ayatollah Ali Khamenei,  Syrian ruler Bashar Assad or Hizballah’s Hassan Nasrallah are planning to hit the Israeli airport with rockets on March 20. But neither is any responsible official prepared to expose the president to the slightest risk.

After all, in the more than 120,000 square kilometers of the Damascus-Baghdad-Amman triangle and the 62,000 square kilometers of the Sinai Peninsula, it may be possible to find a jihadist commander willing to act on an order from al Qaeda leader Ayman al-Zuwahiri to avenge the death of Osama bin Laden in on May 2 two years ago in Pakistan at the hands of American commandos.

Both groups of security experts appreciate that Zuwahiri has the motive for punishing the US president for ordering his death and, for the first time, the capacity to reach him from al Qaeda-controlled territory with surface missiles loaded with poison chemicals. 

Even if their weapon did not touch President Obama, it would be enough for one to explode on an Israeli or Jordanian air field at the time of his arrival for the terrorist organization to chalk up a major strategic feat.
