ISO 1938 UK magazine article

I am searching for an article which was published in the July 1938 issue of an English magazine called “The Nineteeth Century” and was about pacifism.

As an aside curiosity I will mention that I found this article published in that magazine in 1889.

That led me to the British Library and their search page but, after fumbling around there for a while, I still have no idea how to find it.

Maybe there are other places where I could find it. Can anyone help me find it?

Again, it is an article which I believe says pacifism is/was a failure and was published in the July 1938 issue of an English magazine called “The Nineteeth Century”.
