I've read that US Congress wouldn't fund improvements to Pearl Harbour defences, but when FDR based the Pacific Fleet there Congress was forced into action.
Could a similar scenario occur with Wake, Midway and Johnston islands? The USN could station a ship out at thses islands for extended periods and then demand facilities for them? Nothing too serious, a couple of PT boats or a destroyer escort.
Also how would the defence of Wake go if there were some naval forces stationed at the island, a couple of PT boats or a DE? Could they do some handy work in conjunction with the Wildcat sqn and shore guns?
