Hello,

If the UK allied with Germany/Japan in WW2 from a militarily point of view how would it play out?

Lets say WW2 still begins France falls but no Dunkirk, Battle of Britain, Singapore etc. Barabossa still goes ahead as planned but with British forces joining German forces, Pearl Harbor still happens with possibly RAF/RN forces. Germany declares war on America as does the UK.

Would there be any advantages the British Empire had/could bring to the Axis powers to use against the Soviet Union and America? Strong Navy? Forces all over the world? Were British jet engines of significantly higher quality than German ones?

How would the Eastern Front/Pacific theater play out?
