Think about it this way - if Russia had the US Navy's task force near Ukraine, and the level of air dominance that US has in Iran, do you think Russia would do anything differently? Would they, for example, be making 100s - 1000s of daily aerial strikes anywhere in Ukraine?
Because US _does_ have that, and so it _does_ significantly change the calculus. Unless you think it doesn't. In which case, we just disagree.
In the matter of drone production, which was my point, it doesn’t change the calculus. It is evident that short of regime change or popular upheaval Iran can produce or import drones indefinitely and the only thing that can stop it is a ground invasion.
The US Navy or any navy can’t destroy that production from the air.
The evidence is pretty clear on that. We see that is already the case in Ukraine or with Hezbollah and Ansar Allah.
