You can’t defeat Iran, and invading Iran is insane.
But you could beat them at their own missile game …
Take 50 submarines capable of launching cruise missiles and ATACMs and IRBM’s and any hypersonic weapon we might have, conventional warheads.
They can easily fire from beyond range, and get resupplied from beyond Iran’s reach.
Adopt shoot/submerge/scoot strategies, forcing the Iranians to reveal locations from their own anti-missile and counter-missile fires. Again, the Iranians are very unlikely to take out a submarine.
You will build a data model BASED UPON phase 1 fires.
As you build a data model, you can start figuring out WHERE key logistics junctions for the Iranians are located, fiber cable junctions, command/control nodes, the supply chain, etc.
This strategy PHASE 1 returns a data model of the battle field by 30 days in, and no US forces need be killed.
Phase 2 is concentrated targeting of HVT based upon the data gathered. There is risk here for casualties, but you’re not flying blind and your focus of counter air defense will be more precise.
You cycle through this, evaluating the data every 30 day loop.
A few cycles of this and the Iranian situation is bleaker, the USA/allied position better and then Trump can get his “grand deal”.
But IDK, this is a dumb war.
