Being this political cartoon takes an isolationist viewpoint regarding the events leading to World War II, a piece of evidence which would support the cartoon would be the Neutrality Acts of 1935, 1936, and 1937. These acts prevented trade and travel with any aggressive country. These rules are connected to how the US got involved in WWI and therefore was an attempt to prevent that once again.
A challenge to the cartoon would be the Lend-Lease Act which officially allowed the selling of arms on credit to non-aggressive countries. Essentially allowing the US to trade openly with the Allies and most important Great Britain. This act shows the US's hand and reveals who the government wished to side with if we were to enter the war.
The answer would be "The battle of the Bulge". This is also the largest Ardennes Offensive which was the largest battle fought on the Western Front in Europe.
