Some individuals concerned about global terrorism might advocate for the free movement of people and open immigration policies as a means to promote cultural exchange, economic growth, and social cohesion, arguing that allowing diverse populations to interact can help counteract radicalization and foster understanding. They may also believe that open policies can strengthen national security by allowing for better cooperation with international partners and improving intelligence sharing.
Conversely, others may argue for limits on movement and restricted immigration policies as a way to enhance security, fearing that unchecked immigration could facilitate the entry of individuals who might pose a terrorist threat. They may believe that stricter controls are essential to protect citizens and maintain national integrity in an era of heightened global risks.
I find the position advocating for limited movement and restricted immigration more persuasive because the potential risks posed by unregulated entry into a country can undermine public safety and national security, making it necessary to implement measures that prioritize the protection of citizens.
