Dutch are part of the Allies, they are not neutral. Dutch territories have always been valid landing zones for Allied aircraft.
Rule “change” is a clarification and not an actual change, I agree.
Is ANZAC allowed to land fighters on the Phillipeens before either country is at war (in our games Japan usually waits until turn 3 or 4 and launches a massive frontal assault in all directions)? So they are only at war with china, and to help out the Phillipeens, I wanted to land my anzac fighters there, but my friends protested against it.
No - as long as the US is neutral, no other power may move over or on its territories.
Thanks
