It most certainly is. In terms of the U.S.'s own involvement, we floated the idea of Ukraine joining NATO, but then did nothing to ensure it actually happened, and the end result is invasion. Staying neutral on the matter of a straightforward invasion of another country where there is no meaningful "two sides to the issue" analysis to be had is equivalent to materially supporting the invasion. Anyone remotely rational has condemned these actions. True neutrally is only desirable for those who want to continue doing business with the Kremlin or who have other nefarious designs.
