Discussion: States' Rights vs. National Security
Terrorist attacks in the European Union, have highlighted the effects of non-secure borders that have allowed terrorists to cross borders without security checks and attack civilian targets. This has raised questions about the viability of the European Union and its lack of security to protect civilians.
The United States adopted a policy to secure its borders while also securing inter-state travel with the Department of Homeland Security's Real ID program, passed in 2005, but yet to be fully implemented. Americans expect to travel by air within the nation's borders safe and secure. In December 2016, TSA announced that it would enforce the REAL ID program. As a result, states whose driver's license ID's are not compliant by 2018, will not be accepted at TSA Security airports.
