> No system can survive for long if this is widespread. Scientific collaboration can obviously not only survive but is enhanced by the EU dropping its xenophobic institutional barriers to non-EU countries working with them. What you mean is that if European countries realize they can leave the EU and still work together, then the EU itself as a political institution can't survive long. But if you believe that then it is another way of saying the EU isn't actually useful and exists only due to its cartel-like "all or nothing" stance. In which case good riddance, Europeans and the rest of the world can work together much better without it.
