EU bureaucrats in disbelief that words on paper mean little in exigent times.
This is one of the big problems with the EU when it comes to geopolitical issues and security. Way too dependent on diplomacy and then always get surprised when other entities simply break the rules. I guess maybe the lack of foresight is because they are used to lording it over the EU member states (with a couple of exceptions) and then expect non-EU states to be equally complacent.
Instead of wasting time negotiating on price, they should have built manufacturing capacity within EU borders.
