What approach should the U.S. take in negotiations with Russia regarding Ukraine?

According to former U.S. Ambassador to Russia Michael McFaul, the American strategy should not be responsive to Russia's initial positions, as they won't offer concessions in the beginning and will stake out maximalist positions in negotiations. McFaul emphasizes that there is absolutely no evidence that Putin is prepared to provide any concessions in these talks. This assessment suggests the U.S. should maintain a firm stance rather than immediately responding to or accommodating Russia's opening demands, as Putin appears unwilling to compromise on key issues related to the Ukraine conflict.
