Israeli airforce back at it tonight, hitting Iran backed militant groups in Iraq. They did a lot of work against the Iranian air defence network last night, which is exactly what you’d do at the beginning of a longer air campaign. They have an air corridor through Syria and Iraq which can be used to fly close up to Iran and launch stand off munitions, minimizing risk to IAF aircraft. Iran can’t do a thing to prevent this, so their only option to respond is further direct missile and drone attacks from Iran, activating Hezbollah rocket forces in Lebanon, or terrorist attacks in third locations against Israeli civilians.
None of that can secure Iranian skies from further strikes, so it’s really a question of how much damage Israel now intends to inflict on the Mullah’s regime, it’s military and proxy forces, and Iranian CNI.
