“Iran (its terrorists) could launch massive attacks against the Gulf States, or Israel, or the US or against any infidel.”
Well, Israel and the US at least have already developed defensive systems that can handle the cheap Iranian drones quite well. In fact, Israel has transferred some of those systems to Ukraine already, but obviously not enough. Israel is much smaller than Ukraine so they probably do not have a large enough supply to hand over that could protect that whole country. And they must keep enough of their stock for their own protection.
I’m sure Iran will nuke Israel as soon as they have working devices.
