Ukraine, Middle East, North Africa and Security

We have heard a compelling speech from the Chair of the Defence Select Committee, the hon. Member for Penrith and The Border (Rory Stewart), about the importance of investing in our own institutions. Is my hon. Friend suggesting that we also desperately need to invest in the legitimacy and authority of international institutions such as NATO and the chemical weapons convention, so that we have legitimate frameworks within which to intervene in these situations?
