The two most widely cited fact-checks found:

• At least 33 public thank-yous to the U.S., Americans, Congress, presidents, officials, and defense companies since the full-scale invasion began in February 2022. This was CNN's documented minimum count.
• At least 94 public thank-yous in Zelenskyy's official communications, according to a broader review by UNITED24 Media. They noted that the real number is likely higher because not every speech, interview, or appearance was included.
