Ukraine has notched another big victory in its war against Russian aggression: the liberation of the Kherson without a grueling urban battle.

Yet that triumph was met with mixed messages from U.S. President Joe Biden¡¯s administration on a very sensitive subject: whether the Ukrainians should begin peace negotiations with Russia.

The chairman of the Joint Chiefs of Staff, Gen. Mark Milley, argued that the Kyiv government should seek a settlement before the conflict becomes a stalemate like World War I. Other U.S. officials pushed back, saying that Washington would never force Ukrainian President Volodymyr Zelenskyy to negotiate or make concessions. ¡°Nothing about Ukraine without Ukraine,¡± Biden pledged.
