I dunno.
I guess we should show some compasion and empathy. I think a large part of the EU's problems with AZN has been that we were, as our PM said yesterday, "greedy". Great for us. Bad for everyone else. I think we should recognise that we've caused them a problem and do all we can to diplomatically ease tensions without retaliation. They are our friends and neighbours and need our help.
I think anyone with an ounce of sense would realise that if every European country did what we did, we'd all be in a far worse situation than we are now, so I don't think the "EU" are trembling at our success. Personally, I think if we'd gone along with the EU and joined in, there would have been no issue. Sure, we would have gone a little bit slower, but I prefer a cooperative approach in the melting pot that is Europe anyway.
