Why did Ukrainian President Zelensky postpone his trip to Saudi Arabia?

Zelensky's postponement signals his dissatisfaction with how the White House has handled opening talks with Russia. He feels excluded from crucial discussions, as he wasn't properly informed about Trump's conversation with Putin and subsequent peace initiatives. This sentiment is shared across European allies, who feel blindsided after years of close cooperation through the Ramstein process under the Biden administration. By withdrawing his presence, Zelensky is asserting that Ukraine won't be sidelined in negotiations about its own future.
