Until now the US has been keen to drag this war out and wear down Moscow but it would seem that the Kharkiv Offensive marks the moment that they've decided to initiate its endgame. It's a dangerous moment as Putin is also desperate and escalating the stakes by his mobilisation and his recent appeals to Beijing at the SCO meeting in Uzbekistan. If China begins to aid Russia, this war could swing the other direction and again the threat of a global war only intensifies. These are all factors explaining why the West is beginning to push hard and break the stalemate.
