<h1>Political backlash over discriminatory tariffs and sanctions, cross-border expulsions, border tensions, protest detentions, airspace dispute, visa reforms</h1> U.S. political actors criticized recent tariffs and targeted sanctions levied by the U.S. administration against a foreign buyer of Russian oil as discriminatory and damaging to bilateral trade relations, raising potential trade-law and diplomatic concerns. Separate items raise legal issues regarding cross-border expulsions and border-force procedures between two neighboring states, state restraint and joint peace commitments in disputed border areas, and a domestic incident where protesters vandalized a veterans' meeting leading to detentions and potential criminal and human-rights implications. Additional matters include a diplomatic protest over alleged airspace violations, proposed restrictions on student and media visa durations, and prospective reforms to employment-based visa and permanent-residence processes.
