US society is divided, many democrats hate trum and within MAGA there is an anti-war faction.
If there is any attack, their economy will feel it immediately and his inflation-control promis will also be broken.
Iran will have to concentrate on hitting regional bases, oil and gas installations, enemy ships. At the same time Yemen should start, Iraq as well to destroy pipelines and create an international energy crisis.
This scenario is not difficult, we fight at home, many believe in our cause and support us, including people in international community.
EU will feel the pressure, massive amount of refugees should go to start a new life in EU while inflation will increase and energy prices skyrocket.
Just try to control the situation, Keep producing missiles and drones and keep logistic channels open with China, Central Asia, Iraq, Turkey, etc for import and export of needed parts, components or anything.
Turn the war into a nationalist, anti-imperialist and muslim cause, which it is!
