What challenges is Volodymyr Zelensky facing at this critical point in Ukraine's situation?

Volodymyr Zelensky is confronting profound uncertainty amid shifting US policies that directly impact Ukraine's security and future. As Joachim Bitterlich indicates, Zelensky must navigate the geopolitical complexities of potentially reduced American support while maintaining Ukraine's defense against Russian aggression. Zelensky faces the difficult task of developing alternative strategies for Ukraine's survival should Trump's approach alter current security assurances. This situation creates immense pressure on both Zelensky personally and the Ukrainian people collectively, who face an existential threat requiring continued international backing to withstand.
