True-true

I'm not saying hold the island.
Don't waste your ships. Give the enemy a bloody nose (they got that in the first attack) and a black-eye (perhaps a couple of lumps besides) and make him waste his ships. Make him think it needs securing and extra protection beyond what he originally thought.
I was just trying to say....get there....first. Deliver your planes/marine(volunteers?), and ammo/fuel.
Leave and rendezvous with the decoy group on the way back (Lex/Sara) are more important at this point.
The "Alamo" Wake was. A delay, and the more painful they could make it for the Japanese....the more wind out of their sails (momentum lost), the more time gained, the more resources occupied.
Wake's original force did a magnificent job of this with what they had. Had they gotten the extra....who knows how much of Japan's limited fuel/warships/time/soldiers/supplies would've been used up for that "Bird" sanctuary.
Get there, deliver, get out. That was the mission of most sense.
