Border protection refers to the measures and policies implemented by a country to secure its borders from illegal entry, smuggling, and other threats. This includes the use of personnel, technology, and infrastructure to monitor and control the movement of people and goods across borders. Agencies like the U.S. Customs and Border Protection play a crucial role in enforcing these laws and ensuring national security. Effective border protection also involves cooperation with neighboring countries and international organizations to address issues such as human trafficking and drug smuggling. By maintaining secure borders, nations aim to protect their citizens, uphold the rule of law, and facilitate legitimate trade and travel.
