The US has just announced another $8 billion tranche of deadly aid to prolong the war in Ukraine. Even though it has long been clear that Ukraine has lost, a section of the western imperialists are determined to fight to the last drop of Ukrainian blood. Meanwhile, Zelensky, for his own political reasons, like a gambler doubling down, has opened a new, bloody front in Kursk.
It's literally not. That's one argument they make, but the article is about the West pressuring Ukraine to continue fighting. I'm fairly certain they'd continue fighting regardless.
As insurgents, maybe. I doubt they'd be sending cruise missiles over the border if the US wasn't passing them out.
