 Ukrainian President Volodymyr Zelensky arrived at the World Economic Forum in Davos on Tuesday. Zelensky is attending Davos for the first time as president after speaking by video in previous years, top officials from the United States, the European Union, China, the Middle East and beyond are also present. The Ukrainian leader will endeavor to keep his country's long and largely stalemated defense against Russia on the minds of political leaders, just as Israel's war with Hamas, which passed. The 100-day mark this week has siphoned off much of the world's attention in Zelensky, once reticent about leaving his war-torn country. Has recently gone on a whirlwind tour to try to rally support for Ukraine's cause against Russia amid donor fatigue in the West in concerns that former U.S. President Donald Trump, who touted having good relations with Russian President Vladimir Putin, might return to the White House next year.
