While your point is correct that Russia is being depleted, truth is that they are being depleted at an increasingly slower rate. Their military industrial complex has really stepped up and they continue to output more tanks, IFV etc.
Additionally, the Russian fighting machine has become more lethal and dynamic. Guided FAB bombs, Lancets etc. are creating havoc and Ukraine is bleeding many troops.
Our real problem is something different. While Russia is being depleted, Ukraine is being depleted faster. Both in terms of equipment but most importantly manpower. Russia is fighting a war of attrition and they are clearly winning.
In early 2024, Ukraine would lose a village every few weeks. In Q2 it was a few villages per week. Now in Q3, Ukraine is losing a few villages every day. It doesn't take a genius to realize the trend here. Ukraine has simply run out of soldiers to fight this war. A plurality of Ukrainians wants peace negotiations. Thousands of Ukraine men are fleeing the country every week to avoid serving in the Ukrainian army.
We had the chance to end the war and allow Ukraine to win in 2022 and early 2023. The West was too scared to really help Ukraine back then. Any help now is just in vain and lead to more Ukrainians dead. Truly we are fighting Russia till the last Ukrainian, unfortunately.
It's a fallacy that I can't focus on enough that Russia's defense industry drastically increasing the production of MBTs and IFVs. That's completely false.
What Russia is doing is restoring armored vehicles that are left over from the Soviet era because it's much quicker process than building new vehicles from scratch. In order to do this, they are canibilizing other stored vehicles for their components. Russia's rate of NEW vehicles production has only increased a minor amount since the outset of the war. This is largely for 3 reasons.
1. It's extremely time consuming to produce brand new vehicles. This isn't unique to Russia. Anyone who builds modern armored vehicles has long lead times.
2. It's extremely expensive to build new armored vehicles, especially compared to the cost of refurbishing older ones. Even if that means you lose capability (see the turn en masse to T-62s) in the process.
3. It's extremely difficult for Russia to source mass quantities of components that use to come from the West for their modern armored vehicles. Sanctions have had a major impact in that area. It's much easier for them to modernize older Soviet vehicles, that exclusively used Soviet parts made in Russia.
There isn't Western propaganda or cope. There are dozens of open source information spheres out there, using video / photo evidence and satellite imaging, that you can see for yourself, that Russia is grinding it's offensive equipment at an alarming rate.
It is objectively true that Ukraine continues to employ a defense in depth strategy and it prefers to give up land when neccessary to save lives (it has far fewer soldiers than Russia) and equipment, but they aren't doing simply because they are "losing". Every major Russian offensive of the war has cost them hundreds (in some cases thousands) of armored vehicles that they will no longer be able to replace as they dig deeper into the Soviet stockpile and empty out their warehouses.
That's why I've been clamoring for the West to dig deeper in re-vitalize Ukraine's armored units as well. They too are facing attrition, but they are inflicting far more damage on the advancing Russians and slowly, but surely, exhausting their mechanized, offensive capability.
By the end of 2024 I want to see the following additional donations / purchases announced at a minimum...
62 Additional M1A1 Abrams MBTs
50 Additional Leopard 2 MBTs
50 Additional Leopard 1 MBTs
50 Additional AMX-10RCs
200 Additional Bradley M2-ODS IFVs
100 Additional Marder IFVs
100 Additional BMP-1/2 IFVs
50 Additional CV90 IFVs
50 Additional KTO Rosomak IFVs
100 Additional Stryker APCs
200 Additional M113 APCs
300 Additional VAB APCs
300 Additional MRAPS
All of this exists in Western storage / on Western production lines, without impacting any Western military readiness. Ukraine is in the process of conscripting 200,000-300,000 additional soldiers. They are training at least 5 new brigades and replenishing existing ones. The armor I listed above goes an extremely long way. Ukraine has proven capable of trading small amounts of it for large amounts of Russia's "equivalent".
