  • Underestimating the role of American public opinion. Anti-German sentiment was already high, but the telegram amplified it. It’s easy to forget how media framing can shift national mood.
  • Thinking the telegram was a German mastermind. Zimmermann was a diplomat, not a grand strategist. The message was more opportunistic than visionary.
