See grim chaos under dictatorships, say (7)
I believe the answer is:
'see grim chaos under dictatorships say' is the definition.
I can't tell whether this defines the answer.
'see grim chaos' is the wordplay.
'chaos' indicates an anagram.
'seegrim' is an anagram of 'REGIMES'.
Can you help me to learn more?
(Other definitions for regimes that I've seen before include "rules", "Systems of government or courses of treatment", "Governments in power".)
