Answer:
In the diagram we can see a menu in the background with different countries implemented into foods and we can also see multiple American flags. This may represent that America is taking over these countries and that it is as easy for them to take charge. The quote at the bottom 'WELL, I HARDLY KNOW WHICH TO TAKE FIRST' shows that America is powerful enough at this time to take charge and dominate the other countries. It shows how America poses as a threat and has much more military power and wealth.
Hope this helps, have a lovely day! :)
