Even if its an israeli ground invasion only, that's still a massive arms injection --- at the same time the US is supplying a ground war in europe.
A ground war in europe, one in the middle east -- all of the US assets in distant seas, its bombs in distant lands. Pretty good time to be a china on tour.
Procuring two landing craft means Israel has the capability to sustain a sea invasion of the scale required to subdue a 92 million population? It would require something like a modern day Normandy to pull this off.
As far as I can tell, israel is doing everything it can to escalate the situation to a place where the US is forced into it. We'll have to see if it can be avoided.
The problem for iran is that while they may believe the US is unwilling to escalate, and so be happier to go "arms down" -- they won't be allowed to by israel. So they're being forced up the escalation ladder.
There are very many things that they can do which would destabilise US military and economic interests directly. One imagines israel will do everything i can to provoke such a response.
