1939 - Best of enemies

1939, year of infamy
The carving up of Czechoslovakia
France reneges on commitments over the
Eastern end of Europe, leading to a
Free hand for Germany and for Russia
In doing what they like, splitting Poland
In two, half each, even though Herr Hitler
Has written of his hatred of Slavs and
Communists, though Stalin's Soviet Union
Did also confer with the Allies. We
Do not want to deal with them, however
So they've been forced into a pact with them -
The Nazis - who plan to crush our Navy
In secret plans by 1944
