Carl Bildt, former Prime Minister and Foreign Minister of Sweden, shares his perspective from Europe on the Russian invasion of Ukraine.

The worst has come to happen. The Putin invasion of Ukraine that we now see unfolding is the worst outbreak of war that we've had since Hitler invaded Poland in September of 1939. The same motives, the same technique, the same lies leading up to it. What will happen now remains to be seen. Sanctions will have to be imposed very fast and very thoroughly, although that particular policy of deterrence has obviously failed, but it was good to try. We must help the fight in Ukraine. We must treat the Putin regime in the way that it deserves in all single respects. And we are heading bleak days when it comes to the security of Europe in the next few days. Transatlantic solidarity will be absolutely key.
