The aircraft carrier Abraham Lincoln, for example, carries as much municipal infrastructure in the Indian Ocean as many American cities.
The US has $20 billion worth of equipment in the Indian Ocean doing relief work.
An aircraft carrier makes a rather convenient platform for emergency relief. Will thought in the future turn to ways in this "dual use" capability of an aircraft carrier might be explicitly enhanced? I doubt the UN will have enough money to operate its own platform, but the American Empire could use some friends.
