Ukraine war marks paradigm shift on the scale of 9/11, says Liz Truss

Foreign secretary says in Washington that democracies must never again allow authoritarian aggression to grow unchecked

The Russian invasion of Ukraine is causing a paradigm shift on the scale of 9/11 in how democracy will confront future threats, the foreign secretary, Liz Truss, will predict in Washington on Thursday.

She will call for the west to stand up to authoritarian regimes, saying the west must rise to this moment and pledge that it must never allow such aggression to grow unchecked as it had over the past decade.
