How has the United States' position changed regarding Russia and Ukraine?

According to Rachel Maddow, the United States is undergoing an unprecedented shift in international alliances. While no Western leader has met with Vladimir Putin since Russia's invasion of Ukraine three years ago, the U.S. is now apparently taking Russia's side in that conflict. This represents not just a change of position regarding the Ukraine war, but a fundamental realignment in global politics. Maddow emphasizes that the U.S. is now positioning itself against Europe and its allies of the past 80 years, effectively changing sides in the world order in favor of Russia.
