Trump’s ongoing bilateral diplomacy with Zelenskyy, including their July 28 White House meeting focused on Patriot missile production licenses and reviving Russia talks, has not extended to a trilateral leaders’ format. Separate US-Russia and US-Ukraine channels continue amid battlefield stalemate and stalled ceasefire proposals, with no scheduled summit or public appearance bringing all three together. Historical precedent shows leader-level trilateral gatherings remain rare even during active US-brokered negotiations, and the short timeline to 2027 leaves little room for such an event absent a major diplomatic breakthrough. Trader consensus at 94.5% for “No” reflects these structural and timing barriers.
