The Israeli aim here seems to be twofold. First of all, it is to keep the armed forces of Iran and Hezbollah – the Syrian regime’s allies – away from the boundary line of the Golan. The quickest way to do this is to make sure that there is a feasible armed opposition in that area.
Secondly, Israel’s arms proliferation programme is intended to promote its official strategic objective in the region; to “let both sides bleed” in order to prolong the war for as long as possible. Weakening Syria and its allies, Lebanon’s Hezbollah and Iran, is an important goal for Israel and its superpower backer, the United States. Even more important is the goal of making sure that the war carries on.
