"We" was an Australian Aboriginal the day before yesterday, isn't that what you said?
The UK had to pledge to give up its colonial holdings in order for us to step in and rescue them, that was what FDR made Churchill agree to. Now I understand that Dunkirk and hiding down in the Tubeway was really really important to winning the war effort in Britain, and I guess in your case, Australia as well, but hiding 400 ft underground is not winning and ANZAC was a bit on the peripheral side due to low population numbers.
