U.S. Secretary of State Marco Rubio has unveiled a strict new visa policy to block foreign nationals with anti-Israel views from entering the country. Aimed at fighting global antisemitism and safeguarding U.S. interests, the policy will increase scrutiny of individuals promoting hostility or violence against Israel. Rubio emphasized a tough stance against hate and extremism. The move has sparked debate, raising concerns over its impact on freedom of speech and how it may affect foreign activists, academics, and political figures.
