I’ve said before that, in many ways, Vladimir Putin reminds me of a car with no brakes, no steering wheel and no reverse gear; a vehicle careering full speed down the motorway.
Nearly four years after the full-scale invasion of Ukraine there is still no sign of the "Putinmobile" turning off, turning back, or coming to a halt.
He certainly wants his opponents to think that nothing or no-one can force him to change direction: neither European leaders, nor the Trump administration, nor President Zelensky.
But cars need fuel - a constant supply.
And, to fight a war, countries need money - a constant supply.
For now, despite international sanctions, Russia’s government is still able to finance the "special military operation", its war on Ukraine. But economic pressures are building: revenues from oil and gas have been falling, the budget deficit growing.
Even Vladimir Putin admits there are problems, referring to "imbalances in the economy".
"In several sectors, production output not only failed to increase this year but actually decreased,” President Putin said this week. “Are we satisfied with such trends? No."
The big unknown: at what point, if at all, will economic concerns start to influence the Kremlin’s calculations on the battlefield?
