Hypersonic weapons? Poland? UK? Oh dear... From the beginning of the invasion the Russian military capabilities have steadily been deteriorating. The number of equipment losses is well documented, the fact they have been rolling out older and older equipment as well. In terms of missiles their production capabilities have also been analyzed and estimated many times over. At this point Russia is far closer to running out of equipment than invading or attacking any other country.
I especially like the spin about how since the Russians didn't load their strategic bombers to the gills with ordnance, it means that they are running out. To me it seems much more likely that they put in a few unstoppable hypersonic weapons and knew for sure that that would be all it would take.
Of course the Russians are not going to waste missiles for no reason. Nobody would. My guess is that they are saving up plenty for Poland. And maybe a nice big fatty packed with depleted uranium for the farmlands of the British Isles. Shouldn't bother the British very much since they are on record as saying that DU is not a problem.
