• Maritime Zones: Designated areas of the sea or ocean under specific legal jurisdiction, including territorial waters, exclusive economic zones (EEZ), and high seas.
  Example: A country's EEZ extends 200 nautical miles from its coast, where it has rights to resources.

• Choke Points: Narrow, strategic waterways such as straits or canals that are critical for global maritime trade; highly vulnerable to disruption.
  Example: The Strait of Malacca is a major choke point connecting Asia to the Middle East and Africa.

• Global Commons: Areas like the high seas that are not under any single nation's jurisdiction and are governed by international law, allowing free navigation.
  Example: The high seas beyond national EEZs are considered global commons.

• Maritime Power: A nation with a strong navy capable of controlling its coastlines and projecting influence globally; a key factor in geopolitical dominance.
  Example: The United States is a maritime superpower with a blue-water navy.

• Freedom of Navigation: The principle that ships of all nations can traverse international waters and straits without interference, underpinning international maritime law.
  Example: U.S. naval operations often emphasize freedom of navigation in contested areas.

• Blue-Water Navy: A navy capable of operating across deep, open oceans, enabling global reach and power projection.

📊 Synthesis Tables

⚠️ Common Pitfalls & Confusions

1. Confusing "Choke Point" with general shipping routes—choke points are narrow, strategic passages, not entire routes.
2. Assuming all maritime zones have the same level of control—territorial waters differ from EEZs and high seas.
3. Overlooking environmental hazards as a primary cause of disruption—geopolitical conflicts are often more impactful.
4. Misidentifying "global commons" as areas under national control—these are international areas like high seas.
5. Believing control over choke points guarantees absolute dominance—many are subject to international law and regional tensions.
6. Confusing "blue-water navy" with coastal defense navy—blue-water capabilities enable global reach.
7. Underestimating environmental risks such as climate change impacting choke points (e.g., Arctic routes).
