Having declared a caliphate stretching across Iraq and Syria, the Sunni jihadists of ISIS may now pose a threat to the kingdom of Jordan. If they do, Israel will feel its own interests would be directly threatened, and could ultimately intervene.
Watching the Arab Spring degenerate into sectarian slaughter, Israel has sought to protect itself from the chaos, and, above all, avoid being sucked into the tribal, religious, and sectarian conflicts that have been eroding the Sykes-Picot borders and are now dissolving the “countries” established after 1918.
However, the victories of ISIS, its thrust southward, and its open threat to overthrow Jordan’s King Abdullah could change all that. If the ISIS danger to Jordan becomes real and present, Israel may feel compelled to respond.
