Netanyahu didnt approve Trumps attack plans. He wants full fragmentation of Iran.
The first step is to cripple all offensive capabilities and turn Iran into a war torn country with partial collapse of security forces. Thats why they involved NATO. To bomb and destroy as much as possible. Irans AD network isnt working, so they can come and bomb as they like. By taking out the BMs, they wont have to worry about any retaliation. They will bomb all infrastructure of security forces to make it easier to ship in more arms.
They already have thousands of armed agents inside as we've witnessed the past weeks. Second step is to continue arming them with heavier weapons and recruit more agents. Separatist movements, terror groups and other opportunists will take advantage of the situation. Some of the security forces will defect.
Third step is to create civil war by supporting multiple factions, provide arms and logistics to these and have them all fight IRGC, Army and kill each other. The west will provide air cover and continue to bomb IRGC and Army. Factions will take over territory and create safe zones, declare independence. After a couple years of civil war we will have a fragmented Iran with multiple small failed estates.
