Although both sides received foreign military aid, the help that Fascist Italy, Nazi Germany (as part of German involvement in the Spanish Civil War), and neighbouring Portugal gave the rebels was much greater and more effective than the assistance that the Republicans received from the USSR, Mexico, and volunteers of the International Brigades. While the Axis powers wholeheartedly assisted General Franco's military campaign, the governments of France, Britain, and other European powers looked the other way and let the Republican forces die, as the actions of the Non-Intervention Committee would show. Imposed in the name of neutrality, the international isolation of the Spanish Republic ended up favouring the interests of the future Axis Powers.
