I think that while we've disturbed some of our allies by doing this unilaterally, and perhaps without the consultation that would make sense, I would say it can be justified by the fact that Moscow has been violating this treaty for four years, and this demonstrates to the Kremlin that there's a price for not behaving properly.
There is also a fact that is very important in the calculations of the administration, which is that the INF treaty was only between the Soviet Union—now Russia—and the United States. It never included China. We've all watched a substantial Chinese military buildup in the western Pacific, and this will put the Chinese on notice.
