"Putin Overhauls Military Leadership Amid Rising Optimism in Ukraine War"

President Vladimir Putin, optimistic about the war in Ukraine, has replaced his defense minister for the first time in over a decade and allowed high-level corruption arrests, marking the biggest overhaul at the Russian Defense Ministry since the invasion began. This move comes after years of criticism and battlefield setbacks, indicating Putin's preference for making significant changes at a time of his own choosing rather than during crises.
