A German Invasion of the Iberian Peninsula. Note by J.I.C.

Conclusions 11. (a) Spain would resist demands for the passage of troops through her country unless such demands were backed by forces so overwhelming as to make resistance hopeless. (b) Germany has not now the military forces available to constitute such a threat, nor will she have the forces available in the foreseeable future unless Russia collapses a contingency which we believe to have receded to vanishing point. (e) Occupation by Germany of a resistant Spain, or even of a sullenly acquiescent Spain, which had yielded to threat of overwhelming force, would represent a heavy and increasing military, economic and administrative commitment which, under present circumstances, she is unable to meet.
