I guess Zelensky and Putin were unaware of the end and just kept shooting.

Fact check: It wasnt in jest. Here are 53 times Trump said hed end Ukraine war within 24 hours or before taking office
On the campaign trail in 2023 and 2024, Trump said on dozens of occasions, in an entirely serious tone, manner and context, that he would end the war in Ukraine either within 24 hours of his return to the White House or even sooner than that. He said over and over again, including at both presidential debates of 2024, that he would have the war settled when he was president-elect, before his inauguration.
A Friday search of the Roll Call Factba.se database that catalogues Trumps public remarks turned up at least 53 examples of Trump making such comments.
Its sometimes hard to determine the intent of a politicians one-time ad-libs, but this was no jovial ad-lib. Rather, the promise of a rapid end to the war was a sober staple of Trumps pre-written rally remarks. He framed the promise as a key component of his second-term agenda, and he justified it with claims about his credibility as a leader, his history as a peacemaker, and his knowledge of Russian President Vladimir Putin and Ukrainian President Volodymyr Zelensky.
Trump sometimes emphasized that he was speaking literally, scoffing at critics who said he couldnt end the war that fast. Ill get that done within 24 hours. Everyone says, Oh, no, you cant. Absolutely I can. Absolutely I can, he said at one July 2023 rally in Iowa. He said at a Pennsylvania rally later that month: Before I even arrive at the Oval Office, shortly after we all together win the presidency, we will have the horrible war between Russia and Ukraine settled. It will be settled. The war is going to be settled. Ill get them both I know Zelensky, I know Putin, itll be done within 24 hours, you watch. They all say, Thats such a boast. It will be done very quickly.
