But the primary difference between areas within the US borders and areas within Israel's borders is how the consequence materializes.
In the US the expected response would be an investigation, finding the munitions, taking the munition as evidence, finding the owner or user, interviewing people, indicting and convicting the owner, seizing the owners assets or finding the building somehow culpable too, only for the purpose of temporary ownership by the state, not destruction. If something occurred during the investigation or the presence of a law enforcement, the law enforcement may shoot back on the spot.
In Israel, right now the expected response is lobbing a missile at the building and gaslighting everyone that questions that particular approach.
Ah hem. The Second Amendment would like a word...
There is nothing in theory keeping anyone in the United States from owning or even using military grade munitions. Just paperwork. And all too much at that. If you're going to be seizing property, due process. Your due process you seem to be espousing reads "have use military grade munitions -> seize and prosecute".
Those of us that like to safely own and have things that go boom or have military applications would appreciate it if you'd describe due process as it should be, "prosecute, secure beyond reasonable doubt conviction -> seize property", though even that is open to question as the property to be seized should reflect the crime committed. If felony theft is committed, property should transfer to next of kin, or liquidated with proceeds going to next-of-kin.
Order matters.
Besides which, what is the big deal with Israel anyway? Besides people who read way too much Revelations, and think entirely too much of the United States as a lynchpin in that, I've seen very little to recommend keeping up a military industrial pipeline coffer lining exercise in that part of the world. The U.S. is quite literally being the mother of all enablers in that regard.
