Start with Gaza. Egypt isn’t looking to pick a fight at this time. After the ISIS attack, Jordan probably wants no part of this either, so I would keep an eye on the West Bank.
As far as the Golan and South Lebanon, Syria is in no position to do anything so I would focus on Iranian troops throughout the region. Maybe WP them or hit them with some chemical, this way you can blame it on ISIS having Iraq’s “non-existent” chemical weapons. I have always been a fan of taking out someone important then when everyone comes to the funeral, take them out also.
