In recent years, Western governments have invoked the values of universal human rights to justify large-scale military operations. Critical theorists have often responded that these campaigns serve not to promote peace, stability, or prosperity, but to entrench Western economic and political power, often in ways that have been devastating for local populations. However, Russia’s 2022 invasion of Ukraine casts doubt on whether assumptions about Western dominance will continue to furnish adequate accounts of global armed conflict. Critical theorists base many of their views on what is sometimes called ‘memory politics’, meaning that they cite histories of Western militarism, colonialism, racism and economic exploitation as backdrops to current policies. In this article it is argued that they will only be able to explain a conflict like the Ukraine war with credibility by incorporating into their memory politics the left’s own histories of supporting autocratic regimes.
