I suspect you'd find the competent analysts will disagree on the accuracy. These weren't random scud shots, they were precision hits, successfully not taking life.
Israel's lied about its nukes since the 60's. But they're clubs, cudgels, bludgeons. In numbers alone, with this kind of accuracy, Iran could be just as devastating to the Zionist state as vice versa. And I think the Mossad knows it.
For your ground troops argument, Israel has tacticals, but not enough bodies. My answer there is little more than remember what happened with the seven-year Iran-Iraq war.
The cockiness of our retired ex-mili talking heads on the TV shows, swayed by a decidedly Israel-heavy influence, departs from realism. Same way those idiots have absolutely no clue how far Russia has come in the last 30 years.
Except for the very few who are privy to things like their complete electronic disabling of one of our ships, or those who saw what they were capable of in Syria. Those guys understand and are scrambling behind the scenes.
Optimistically, though, I think it's irrelevant, because with particular credit to Trump, we've gotten a lot better at averting anything serious by going backchannel, saving lives in ways the talking heads won't understand for possibly years to come.
Which is fine, as long as the job gets done first. It's kept Bibi from going more bezerko than he already has. It's worth it.
