100 days, thousands dead, millions displaced, billions in destruction, countless lives touched: Russia's war in Ukraine looks less likely to end today than it did when it began on Feb. 24.

The big picture: With the prospect for meaningful peace talks virtually non-existent, the war appears set to continue for weeks or months longer.
