Here’s a concise update on the topic you asked about.
- Germany’s policy of unrestricted submarine warfare dates to early 1917, when the German high command resumed unrestricted U-boat attacks to try to break the Allied blockade and shorten the war. This move helped push the United States toward entering World War I.[2][6][7]
- The resumption followed previous limits like the Sussex Pledge and occurred amid strategic pressures from Britain’s blockade and Russia’s situation. The decision is widely regarded as a turning point that influenced the course of the war.[4][6]
- Historical summaries note that Germany believed unrestricted submarine warfare could force a quick British surrender, but it ultimately contributed to American involvement and shifted the balance toward the Allies.[3][9]
