Depending on what Germany purchased and which German subs survived, and providing that none of those subs are in SZ106, it may be possible to save the UK battleship or to make sinking it unattractive by moving it to SZ123, and landing the Scottish and the French fighter on Iceland, assuming the English planes are used for Taranto. If Germany didn’t attack SZ106 or lost that battle, 2 Canadians can be sailed to Iceland to reinforce it against an invasion. Any surviving UK destroyers could also go to SZ123. In case of a J1 DOW, the US can further reinforce Iceland and/or SZ123.
If the Germans then still want to destroy the British battleship, they will need to send most or all of their warships. The US can help by building an Atlantic fleet poised to take out the Germans in SZ123, and the Axis can then prevent that only by postponing Japan’s DOW until turn 3.
