I rebase Italian NAV to Netherlands, Germany has NAV, FTR2 and FTR3 available to attack North Sea. Unless FTR3 is needed for ground strike, but I doubt.
Germany has 2x Bf109 if CW try to mess with German spear head and 2x Ju88 for ground strike / ground support. Stukas are out of range for Paris so they are disorganized.
If your attack is going really well, it's an ambush.
