In page Moa Martinson:

"

Over six years Martinson had published eight books and had gained most critics' respect.[citation needed] In September 1939, World War II broke out, which she saw as the biggest threat to the working class. In her opinion, the non-socialist ruling countries were sending out workers to fight for values they did not share. When it came to Soviet participation in the war, Martinson had a different opinion and believed that Russian workers were defending their revolution.[1]
