If the Solomon Islands campaign had gone worse

What if Japan had concentrated its battleships and won a decisive surface battle in the Solomons?

The setback would be painful, but the United States would rebuild and return rather than abandon the campaign.

A concentrated Japanese surface victory would make the Solomon Islands campaign painfully worse for the United States. One lost battle would still be unlikely to force American withdrawal from the wider war. American industry could replace ships and equipment while its political commitment remained intact. Japan might win a major action without removing its opponent's capacity to rebuild and return.
