Oleksandr Syrsky, right, and Roman Mashovets, deputy head of the Presidential Office, look at a map during their visit to the front-line city of Kupiansk, Kharkiv region, Ukraine, Thursday, Nov. 30, 2023. Zelenskyy says the war with Russia is in a new stage, with winter expected to complicate fighting after a summer counteroffensive that failed to produce desired results due to enduring shortages of weapons and ground forces. Despite the setbacks, however, he says in an interview with The Associated Press that "we are not backing down." (AP Photo/Efrem Lukatsky)
