I'd like to thank the member for his question.
We have been very clear that every inch of NATO territory would be defended. We've put in place absolutely robust defence plans, which were implemented seamlessly. If there were a use of nuclear or chemical weapons against NATO territory, there would absolutely be a response.
Certainly, use of nuclear or chemical weapons on Ukrainian territory would also cross a red line globally, given that the impact would be felt elsewhere, but this is not the sort of decision that is taken beforehand. The alliance would take the decisions required immediately when required.
