What would happen if the modern US Navy and all its overseas bases appeared in 1950?
Short answerWar could begin immediately, and widely dispersed modern technology might fall into hands the United States did not choose.
NotesThe counterfactual places the modern US Navy, its ships, and its overseas bases into 1950. Immediate crises would follow because facilities suddenly occupied Japanese, British, German, and other territory without the later alliance framework that legitimized them. Host governments might seize or attack the bases, with Japan offered as the clearest example. Modern weapons and support technology would then be distributed across many locations where the United States could not control who acquired them. A military network depends on political agreements and host-state consent as much as on the equipment inside each base.
