"Ukraine proposes ending this war through direct engagement between us - and you. I am proposing a meeting," Zelensky said in the letter. "Ukraine is ready for a full ceasefire for the duration of the negotiations," he added.

The letter, which is somewhat lengthy at one point says, "The choice is yours now. Enough of war" and then spells out that "Ukraine proposes to end this war."

"This must be done honestly, with dignity, and with guarantees that the war will not be reignited," Zelensky added. And then interestingly, "We see that the United States is fully focused on the issue of Iran, and it would be wrong to simply wait until the war in Europe returns to the center of its attention."
