Russia has the ability to keep making artillery and basic missiles forever more and it also has unlimited man power
People keep saying this, but I am not so sure about it.
For a start, Russia's armaments are not by any means all of them useable: there are reports that as much as 50% of what they have stockpiled isn't fit for purpose for one reason or another. And in cold fact, they don't have that many or that brilliant arms manufactories: the country has not been able to afford them. The USA and even Britain have far larger and more efficient ones, to say nothing of Germany and France.
With regard to the unlimited manpower: from 1992 to 2012, and again since 2016, Russia's death rate has exceeded its birth rate, even not counting the 140,000 or more men who have so far died in Putin's war (and whose deaths have been denied by Putin's regime) and since the most recent census; and I frankly disbelieve the Russian census figures anyway, because they inherited their census system from the USSR and the figures from the USSR were patent fiction, or to put it politely massaged to give the best possible impression: inflating the population figure meant more money from central government funds so of course there was a perfectly sensible motive to lie about how many people lived in the area... Then there are the Russians fleeing the draft and the war: 200,000 to Kazakhstan, 150,000 to Turkey, 100,000 to Georgia, 50,000 to each of Armenia and Uzbekistan, 30,000 to each of Israel, Finland and Kyrgystan, 20,000 to Tajikstan, 10,000 to Argentina... It all adds up. (Yes, Russia is getting refugees and people forced to move there from Ukraine: old men, women and children, not men of fighting age. Not a good exchange for the ones they have lost.)
And that not-unlimited manpower is at present untrained or was trained more than ten years ago. Most of Russia's crack trained troops were seen off by Ukraine during the first few weeks of this war (while their tanks ceased to function and tank-jams built up behind the ones that could neither move under their own steam nor be moved out of the way because nothing could get to them to shift them); they have put the people qualified to train new troops onto the front line, and many of them have been killed. The Wagner Group technique of forcing badly armed and untrained men to advance against a skilled and armed enemy to be mown down is not going to be a great help to the Russian cause in the long term, and hasn't been even in the short term, when Russian advances are measured in metres rather than kilometres.
