My personal attitude, wholly consistent with that of my Church, is that I believe in peace on earth, good will to men, and that no country has a right to interfere in the internal affairs of any other country. I recognize the right of no church to ask armed intervention by this country in the affairs of another merely for the defense of the rights of a church. ~Governor Alfred E. Smith, c. 1927

The rights to which he was referring were those of Catholics in Mexico being persecuted by the revolutionary government.  Quite apart from anything else relating specifically to the “religious issue” Smith was addressing, I thought this statement deserved special attention.

He restates this conviction again at the end of the article:

I believe in the principled noninterference by this country in the internal affairs of other nations and that we should stand steadfastly against any such interference by whomsoever it may be urged.
