"Defending Ukraine's sovereignty and territorial integrity is about much more than standing up for one nation's right to choose its own path, fundamental as that right is. It's also about protecting an international order where no nation can redraw the borders of another by force. If we fail to defend this principle when the Kremlin is so flagrantly violating it, we send a message to aggressors everywhere that they can ignore it, too. We put every country at risk. We open the door to a less secure, a less peaceful world. We see what that world looks like in the parts of Ukraine controlled by Russian forces. Wherever the Russian tide recedes, we discover the horror that's left in its wake."
