Very clever cartoon, but who is the one spanking Australia? What country has a white flag with a red cross?
Norway is blue with a red cross on a blue cross, Finland is a blue cross on a white flag, Denmark has a white cross on a red flag.
I guess it must be England. I think the English flag is a red cross on a white field. It is part of the "Union Jack". And the monocle seems to suggest England as well.
