We have contained Russian expansion in Europe by drawing definite lines. and by backing these lines with arms and men. The lines have remained inviolate.

President Eisenhower sent his message on Formosa and the Pescadores to the Congress. and in subsequent actionand in a fine show of bipartisan unitythe Congress drew a line in that area.
