We have indeed given Ukraine just enough not to be defeated. For instance we gave them exactly 31 M1 tanks - we have over Three thousand in storage - hardly providing "every kind of weaponry." However, I believe the "Biden strategy" was hardly Machiavellian, but rather simple fecklessness out some sort of fear they would be faced with some form of retaliation that would be difficult to manage. After all, the war effort was led by Jake Sullivan - a man with zero military or diplomatic experience (rather like Trump's chief negotiator). However, If the Biden administration's actual strategy was to prolong a conflict using the blood and hopes of Ukrainians as munitions, then I find that utterly reprehensible.
I find the blame Ukraine crowd who has assumed control of this country's strategic engagement equally reprehensible and perhaps even worse. They, from our president on down and abetted by his allies in social media like Tucker Carlson, simply lie while the administration's supporters blindly applaud. This war is not the fault of Ukraine. The blame America crowd on the right (how that worm has turned) is also loudly pointing fingers, but this war was not caused by Zelensky, or the Ukrainian people, or the CIA, or any other convenient imagined perpetrator - just Putin.
The surest way to conclude this conflict in a manner that is in our national interests is to provide Ukraine with the means to make it impossible for Russia to achieve its strategic goals. The vast majority of that materiel is sitting in this country in warehouses - materiel our military will never use. I suspect merely turning on that tap would be enough to force the Russians into a very prompt accommodation to try and hang on to what they currently occupy.
Sadly, I do not believe this administration has a perception of a stable, democratic Europe as a key partner - seemingly preferring instead the vague assurances of the KGB thug cowering in Moscow.
