That's only necessary if you want to be careful. It does if you want to ship raw materials and goods to and fro, especially via sea lanes. It is if you want to get access to the sources of raw materials and can place troops in those areas to prevent someone else from getting access to them. That was a large part of the context of WW2 in the Pacific.
