World powers (or parents) who too stridently claim they're doing it all 'for the little ones' invariably are not.
One case in point, Great Britain and her Allies.
Britain never actually conducted its war in 1914-1918 - or the peace process in 1919 - with a prime objective the protecting of the rights of 'poor little Belgium'.
Ditto for Belgium, and a dozen other small nations, in 1939-1945 and afterwards.
Henry Dawson bought into the propaganda claim in 1914-1918 --- but not again in 1940.
His response was to set "The other Manhattan Project" in motion....
