An incident would not have been needed-Pearl Harbour still would have happened, just without Hitler declaring war on the US. The Battle Of The Atlantic would still have been won by the Allies, it just would have taken longer without the US fully committing to it. US participation would still have increased though, and if Germany did not declare war (which they should not, to make this scenario more likely), the US would have declared war on Germany in 1943. It might have been a different situation with a truce though.
