'You have no cards'. 'Just surrender for peace, Russia cannot lose'."

Today Zelensky played the King of Drones."This, then, is the message Ukrainian delegates carry as they arrive in Istanbul for a fresh round of ceasefire negotiations with representatives from the Kremlin: Ukraine is still in the fight.
The Americans "begin acting as if their role is to negotiate for us the softest possible terms of surrender," the government official told Svyatoslav Khomenko.
