Who's winning the war? As Zhou Enlai might have said, it's too early to tell for certain.
Who was winning the Battle of Marengo? The perception would chiefly depend upon when the question was asked.
Should Russian losses in armor be attributed only to alleged Russian incompetence or to basic vulnerabilities of armor in modern war?
I suspect that the best explanation is likely a combination of factors.
In my view, when armored vehicles become exposed to a broad range of modern anti-armor weapons, losses are inevitable.
If Iraq had many of the most advanced anti-armor weapons when it was invaded by the USA, US armor losses would have been higher.
My impression (which is partly based upon the experiences of friends or acquaintances who served in the Russian armed forces)
is that the Russian Army is generally not very efficient, apart from a few elite units. So I am hardly surprised that most Russian
soldiers may have been far from prepared at first to deal with harsh realities of fighting a hostile population in Ukraine.
I had a friend (a member of the intelligentsia) in St. Petersburg (his mother was a curator at the Hermitage Museum), who told me
that he was terrified of being conscripted into the army because he did not expect to survive. He said that one of his friends, a
conscript, had been beaten to death in a brutal ritual of hazing in the army. He said that his family could not afford the bribes
needed for him for avoid conscription. His hope was to marry a young woman with a foreign passport and leave Russia.
He asked me to help him. But I could not give him the relationship that he sought, and so we parted ways.
Wherever he may be today, I feel sure that he would not wish to die--or to kill anyone--in Putin's war.
A Russian woman friend said: "Putin does not stand for all Russia any more than Hitler (an Austrian) stood for all Germany."
