The ethics of foreign intervention

Hosted by the Centre for Philosophy of Natural and Social Science
In-person and online public event (Old Theatre, Old Building)
Tuesday 5 May 2026 6.30pm - 8pm

The US capture of President Nicolás Maduro in January 2026 and the US–Israeli military campaign against Iran have thrust foreign intervention back to the centre of global debate. These events raise profound philosophical questions. When, if ever, is it permissible for states to intervene militarily in the affairs of another? Can intervention be justified on humanitarian grounds even when it violates international law? Do the intentions of the interveners need to be moral for the intervention itself to be moral? And can foreign intervention ever truly serve the interests of those it claims to protect?

Join four philosophers as they bring rigorous ethical analysis to bear on these urgent questions.
