The stated Russian military goals are the "liberation" of the Donbass region and to enforce Ukraine's neutrality (i.e prevent it from joining any military alliance inimical to Russia). With the second goal, there is also the hope that future Ukrainian governments may not be as hostile to Russia as the current Ukrainian leaders and future Ukraine-Russia relations may be normalised as it was in the pre-Zelensky era. Deliberately targeting civilians, with a genocide in mind, makes that highly unlikely.

Note that for the Israeli-right, genocide is the goal because their zionist ideology is based on the settler-coloniser philosophy, and the population of the Palestinian muslims currently outnumber the Israeli Jews (when you include Palestinians that are refugees too, who have a "right to return"). The Palestinians also have a higher birth rate than the Israelis. This is a huge obstacle to the one-state solution - even the Israeli moderates on either political spectrum fear to make Palestinians Israeli citizens (which is one way of ending the conflict) as they fear Israeli Jews would then become a minority. The Israeli-right's solution to this is to make the Palestinian muslims a minority in their own land. (Akin to what the settler-coloniser Europeans did in Canada, USA, Australia etc. with the native population - this is corroborated by a UN probe that says Palestinian children and Babies were ‘special targets’ of Israeli killings - https://www.rt.com/india/642399-israel-gaza-babies-targets/ ). Moreover, as the Israeli-right are mostly religious fundamentalists and have already amended the law declaring Israel to be a Jewish state, they are also resolutely opposed to making Israel a secular state. Thus, in their political vision of Israel, only Jews can ever be a first-class citizen, while non-Jews are always meant to have lesser political rights.

> I think there are complex factors at play that prevent an actual total annihilation attack on the tail, even though it seems like it should be well within capabilities.

It's not about military capabilities but the political repercussions. NATO cannot supply enough weapons to Ukraine till they shift to a war-time mode. Moreover, they cannot allow Ukraine to use their territory to attack Russia, which is needed for successfully executing such an operation. (They have been "experimenting" in this area by ignoring Ukraine's drone intrusions into their airspace, as the drones move towards Russian assets). And you also have to ensure that you don't push the Russians into a corner as they are a nuclear weapon state.

With Iran, it is true that the Americans do have the capabilities to launch such an attack successfully. However, American allies - Iran's neighbours - fear that they will be caught in between the attack and bear the brunt of Iran's retaliatory attacks, specifically on their industry (oil and gas).

Thus, in both cases, it is mostly politics that holds them back.

For me, the most interesting bit of the article is this tid-bit:

> To survive in contested environments, the Army must transition from a centralized hub-and-spoke sustainment model to a decentralized network of smaller, dispersed, mobile, and signature-managed nodes. Sustainment elements must be capable of relocating with the same frequency as maneuver battalion tactical operations centers, while distributed caching of fuel, water, and ammunition across concealed locations should replace the current reliance on large, centralized supply dumps. This transformation must be paired with deliberate investment in camouflage, concealment, and deception tailored to sustainment operations.

That sounds very much like how the current Iranian military and para-military organisations are with their underground bunkers, warehouses and tunnels, with the ability to make independent command decisions in the absence of orders from central command. Even Iran's proxy, Hezbollah, is somewhat modelled similarly and that is why Israel's attack on Hezbollah's leadership (the pager bombing) hasn't had the impact that the Israelis hoped for - they are still bogged down fighting them in Lebanon.
