If the Jews can slowly withdraw to the point where ISIS commits their “reserves”, there is going to be a shortage of virgins in jihadi paradise.
ISIS won’t attack through the Golan. Ultimately they would have to join in alliance with Hizbollah (or attack and destroy Hizbollah) in order to attack Israel through Lebanon. Again, the terrain is not to their advantage, neither is the technological edge. The big threat might emerge if ISIS turns its attention to Jordan, as the PA would gladly turn into their lane, or ISIS would instead annihilate the PA.
Y’know, that doesn’t sound that bad to me.
Again, the Israelis have a technological edge. They also have Egypt and Saudi Arabia as neighbors to the south, and the likelihood of either of those states starting something with Israel is vanishingly small. The only argument for Israel NOT to strike Iran is that, while Iran remains a threat to everyone else, Israel is the Arab states’ best option.
