It is a common hope that Russia’s war with Ukraine will erode domestic support for the Kremlin. This column uses individual-level survey data to show instead that the invasion produced a sharp and enduring surge in pro-Kremlin sentiment. The subsequent partial mobilisation only briefly depressed support. Russians living abroad, however, became markedly more critical of Putin following the invasion. The findings suggest that hopes for regime change from within, driven by public war-weariness, are likely misplaced at least in the near term.
