Well better weather puts it outside the scope of this forum, also this assumes that you buy the claim that it was the Balkans that somehow delayed Barbarossa and not German logistics and also that it was the weather that derailed Barbarossa all by itself, rather than the Wehrmacht reaching the maximum range their supply system could support while having underestimated the strength of the Red Army by a factor of three or four.My thinking on Dunkirk is this. If there is no evacuation, then there is a least a possibility that in early 1941, the UK decide against sending troops to Greece and this (in combination with better Spring weather) enables Barbarossa to start 6 - 8 weeks earlier. The loss of the additional men in Europe if there is no evacuation may 1. make the British more careful with conserving manpower and 2. more gun shy in terms of putting men on the continent.
