For three decades, President Aleksandr Lukashenko of Belarus, a former Soviet nation in Eastern Europe, ruled with an iron fist. But pressure has mounted on him in the past year and a half. After a contested election in 2020, the European Union enacted sanctions and refused to recognize his leadership. In the hopes of bringing the bloc to the negotiating table, Mr. Lukashenko has engineered a migrant crisis on the Poland-Belarus border, where thousands from the Middle East, Africa and Asia have converged. What are the conditions like for those at the border, and will Mr. Lukashenko’s political gamble reap his desired results? Guests: Monika Pronczuk, a reporter covering the European Union for The New York Times; and Anton Troianovski, the Moscow bureau chief for The New York Times.
