While not technically 'Small Wars', an interesting consequence of weak government and failing infrastructure. Can we expect to see this elsewhere, as more nations teeter on the edge of being 'Failed States'?

TEGUCIGALPA, Honduras (AP) -- Investors can begin construction in six months on three privately run cities in Honduras that will have their own police, laws, government and tax systems now that the government has signed a memorandum of agreement approving the project.
The project's aim is to strengthen Honduras' weak government and failing infrastructure, overwhelmed by corruption, drug-related crime and lingering political instability after a 2009 coup.
The "model cities" will have their own judiciary, laws, governments and police forces. They also will be empowered to sign international agreements on trade and investment and set their own immigration policy.

Historical footnote

A city-state is an independent or autonomous entity whose territory consists of a city which is not administered as a part of another local government. A city-state can also be defined as a central city and its surrounding villages, which together follow the same law, have one form of government, and share languages, religious beliefs, and ways of life. Today, only three independent, sovereign city-states exist: Monaco, Singapore, and the Vatican City.
