Also I would argue that Russia has revealed its conventional army to be weaker than large majority of us believed. At the start of this thread the end of the campaign was being being forecast as a quick decisive victory by most. Very few gave Ukraine any chance of winning.
Yes it has moved the goalposts. For example Russia has a huge numbers of tanks, (I think more than any other single country) but they find themselves now engaged in almost a First World war trench campaign.
They also have a huge artillery capability, which they have fallen back on in Ukraine as well as Syria etc. This shows that the days of artillery and attrition are not yet over in prolonged campaigns and also the importance of maintaining ammunition supply.
It is likely that the US is the only nation which can successfully carry out a rapid campaign and a factor in that is they spend huge sums of money on logistics to back up what is going on on the ground. Russia's logistics have failed badly.
The US defence annual spend is more than the other top ten countries put together which includes China and Russia although China has massively increased its spending over the last two decades.
I read the other day that the US air force alone could probably end the war in Ukraine within a week if they wished to, such is the position Russia finds itself, but of course with extreme consequences.
