It's global in so much as the global powers that have stakes in the outcome. Russia has been a cancer upon the international community for too long. Zelensky has given western nations a key ally in potentially bringing it all down around Putin's head.

It's possible Putin could do some serious stupid shit in the coming year if Ukraine's counter offensive really makes gains. If that happens, it will definitely become a global conflict. I'd like to think Putin, or at the very least his top officials, aren't THAT crazy.
