Perhaps, but why then invoke the just war theory as he did? Either way, that statement he made is still false.
My thoughts on that article though has little to do with that statement. I think what we see on display in that article is the author slowly coming to the realization that the American (and conservative Catholic) pro-life political stance has been highly hypocritical and narrowly focused. Even misguided, although he doesn't seem to be at the misguided viewpoint yet. It is as if he is suddenly discovering the "seamless garment" or the consistent ethic of life, that is so often missing among those who claim to be "pro-life."
I also disagree with how he characterizes what is occuring in Ukraine and his desire to connect it with all the other conflicts he mentions, especially the Israel/Palestine conflict. There are clear differences (differences that matter, especially when taking a philosophical approach) and he doesn't acknowledge those differences.
