Where an expanded British forward base should start

Would Diego Garcia, Ascension, or another overseas territory make a useful expanded British garrison base?

The Falkland Islands are the strongest starting point because Britain already has major infrastructure there; Diego Garcia could be joint with the United States, while Bahrain and Singapore are easier established options elsewhere.

The Falkland Islands are the logical first site for a larger South Atlantic or South American posture because a significant base already exists there. Building from that foundation would be cheaper than starting an entirely new garrison. Diego Garcia might support a joint arrangement with the United States, though political and logistical ownership would differ. Bahrain and Singapore are established locations that may be easier to sustain in other regions than a newly created base.
