Ukraine wasn't hosting foreign troops (except Russian troops, some of whom were were the spearhead of the invasion) when the Russo-Ukrainian war started with the Russian invasion in 2014.

(They did start hosting some that were involved in training and advisory assignments after the war started and before the major escalation in 2022, but those can hardly justify the war which started with the 2014 invasion.)

In all “honest” how is that relevant when Ukraine never did that nor was US willing to deploy their troops there to begin with. To what end? Not a single US administration between 1990 and 2022 was particularly antagonistic or expansionist towards Russia..
