With so many Allied fleet units in the Far East, could Germany launch Operation Sea Lion?
Short answerNo easy opportunity appears: France, invasion logistics, a mobilized coalition, and a large British home garrison still stand in the way.
NotesGermany could not exploit the Asian deployment with an easy invasion of Britain. It would first have to defeat France, assemble the shipping and supplies for an amphibious operation, and face a coalition already mobilized for war. Britain would not send every land formation or resource to the Far East. A large home garrison would remain, so the movement of major fleet units does not create an undefended island.
