It’s not an escalation for two sovereign, allied countries to provide weapons to one another when one of them is invaded by a country attempting an annexation and genocide. The only thing escalating is Russia’s whining because they can’t even afford modern tanks.
I’m not worried about WWIII starting at all. Russia is fronting like they’re going to do something and have any cards left to play. They don’t. They fucked around and now they are in the finding out phase.
