US President Joe Biden is expected to formally recognize the massacre of Armenians by the Ottoman Empire during the first world war as an act of genocides. The Guardian reports that the anticipated move – something Biden had pledged to do as a candidate – could though further complicate an already tense relationship with the Turkish leader, Recep Tayyip Erdoğan. Biden’s predecessors have avoided using “genocide” in the annual Armenian Genocide Remembrance Day proclamation but lawmakers and Armenian-American activists are lobbying him become the first US president to do so. Turkey’s foreign minister has meanwhile already warned the Biden administration that recognition would “harm” US-Turkey ties.
