In the last three days we have seen Ukraine shoot stormshadows or the like to several facilities. The strategy of raising the cost of being at war, while not directly attacking civilian objectives sound like a decen plan to show Ruzzia that they also have something to loose by continuing the war. The latests or so... on bunker on which North Korean commanders were identified to be, an oil depot and a large weapons depot.
Ruzzia, thanks to ATACAMS, needs to spread more the depots and have their planes farther away from the front.
BTW... apparently the Ruzzian backed Al-Asad forces are experimenting... let's call it some "setback" in Aleppo. Ruzzia may have to diver some forces or loose Siria.
Russia has demonstrated that they can turn Ukraine to dust any time they want with their missile attack on Dnipro... and all of Europe at the same time. All they need is to get triggered the right way. And Trump is even proposing that rather than moving out of Ukraine, the US moves IN... to keep the peace, of course.
What else do we need to turn this war into WW3?
Ruzzia has not proven anything. The fact that they have MIRV capable rockets is well know since many decades ago. But destroy is not take. Destroy brings on you unlimited international fallback and possibly a full blown US intervention or even direct attack. Using nukes is likely to generate radion in Ukraine but also in Ruzzia itself and potentially towards NATO countries, in which case... Ruzzia would be at war with NATO. This is one of many reasons why Putin is not using these weapons.
So no... Ruzzia cannot do what they would like to.
