This red revolution is uncertain (7)

I believe the answer is:

dithers

I'm a little stuck... Click here to teach me more about this clue!

'is uncertain' is the definition.
I can't judge whether this definition defines the answer.

'this red revolution' is the wordplay.
'revolution' indicates anagramming the letters.
'this'+'red'='thisred'
'thisred' with letters rearranged gives 'DITHERS'.

Can you help me to learn more?

(Other definitions for dithers that I've seen before include "Flaps, wavers" , "Hesitates indecisively" .)
