What is the purpose of the international advertising campaigns being discussed by Homeland Security Secretary Kristi Noem?

Homeland Security Secretary Kristi Noem explains that the ads will be running both domestically and internationally around the world. These advertising campaigns are designed to reinforce America's immigration policies and deter illegal immigration by clearly communicating U.S. border enforcement strategies to potential migrants globally. The broader context suggests these ads are part of an effort that has already shown encouraging results, with Noem referencing decreasing migrant encounters. This media strategy complements the administration's commitment to upholding immigration laws while addressing challenges from sanctuary jurisdictions that may undermine federal enforcement efforts.
