In this episode I pause to take stock of the Ukraine war: what we know and don't know. Most importantly, we don't know what it will take to bring this war to a close, or at least to a cease-fire. We know about about the costs of the war for both sides, but not the tipping point at which interest in negotiations will emerge. Are we headed to a stalemate or an at least partial Ukraine success in its upcoming counteroffensive? In the end, war weariness may be the crucial factor in stopping the fighting.
