Is the enforcement of laws by the Coast Guard limited to U.S. waters?

The enforcement of laws by the Coast Guard is not limited to U.S. waters, which makes the selected answer correct. The Coast Guard has a mandate that extends to international waters and has the authority to enforce U.S. laws as well as international treaties on the high seas. This capability is crucial for various missions, including drug interdiction, migrant interdiction, and environmental protection, and reflects the Coast Guard's role in contributing to national and international security.

In international waters, the Coast Guard can perform its duties in coordination with other nations and often works under various agreements to enforce laws that have been established for maritime safety, security, and environmental protection. This broader authority allows the Coast Guard to effectively combat activities like illegal fishing, human trafficking, and drug smuggling, which may occur outside U.S. territorial jurisdiction.

This context showcases the Coast Guard's significant operational reach and responsibility beyond just the limits of U.S. waters, reinforcing why the answer "No" is accurate.
