Hmm... if I read you correctly that would imply that AES-256 with a key 
containing 128 bits of entropy is less secure than AES-128 with a key 
containing 128 bits of entropy. Do you know of a document where this 
would be explained?

When Germany invaded Czechoslovakia and Poland, its declared 
justification
was to free the Germans living in those countries from the tyranny of 
the
Czech and Polish governments. When Germany invaded the Soviet Union in
1941, one of its declared purposes was to "liberate" the Russian people
from communist tyranny.
