Earlier quoted context omitted.
I understand what you say is true in theory, but does this mean the US will deploy fewer troops in NATO theaters, in practice?
IMO it's still not certain NATO will hold together if Putin decides to attack the Baltic states or Poland. Many NATO countries will have sizeable factions of their electorate saying to not get involved. The fact that Ukraine hasn't been easy for him makes it less likely that Putin will attempt that, but it's clearly been on his mind.
There is a reason forces of core NATO states farther from the Eastern flank are deployed to Poland and the Baltic states; it is practically impossible for Russia to attack them without attacking the forces of core NATO states, not just in a "legally, under Article 5, we must treat this as an attack" way, but in a "Russian troops are killing troops of those states" way.
