During a press conference on March 2, Zimmermann shocked many by publicly acknowledging his role in sending the controversial telegram. This admission was viewed by Lansing as a significant misstep for someone involved in complex international operations. It raised eyebrows, especially since the telegram's content was already questionable.

Zimmermann's decision to come forward was deemed even more reckless than the original message itself. By confirming his involvement, he revealed a lack of caution that many couldn't believe, considering the high stakes of diplomatic maneuvering during that tense period. The blunder highlighted both the message's folly and the implications of openly admitting to it.
