Independence and interdependence

Nicola Sturgeon writing in The Guardian today, on the event of Britain delivering its article 50 notification:

I believe in the independence of nations – Scotland included. But I believe just as strongly in the interdependence of nations – the need for countries to work together to tackle challenges and seize opportunities that few can do alone. That is why an independent Scotland would always seek to work closely with others, across the British Isles and beyond. So it is the fact that 29 March marks the point at which the UK starts to turn its back on almost half a century of close cooperation with its partners on the European mainland that makes it so dispiriting.
