Maintain existing overseas bases before opening new ones

Should any countries open new major overseas naval bases, and where?

Most should first maintain, improve, and retain the overseas bases they already possess.

The answer treats basing as a long-term infrastructure commitment rather than a map of aspirational footholds. A port only delivers strategic value when its docks, support services, stores, and local agreements remain usable. Existing facilities therefore need maintenance, investment, and political protection before a navy takes on another expensive overseas base. An announced location does not amount to a durable overseas presence unless the supporting infrastructure remains effective.
