Acting around America, soaking (7)

I believe the answer is:

dousing

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

'soaking' is the definition.
('douse' can be a synonym of 'soak')

'acting around america' is the wordplay.
'acting' becomes 'doing' (I can't explain this - if you can you should believe this answer much more).
'around' means one lot of letters goes inside another.
'america' becomes 'US' (United States).
'doing' enclosing 'us' is 'DOUSING'.

Can you help me to learn more?

(Another definition for dousing that I've seen is " Extinguishing (light)".)

I've seen this clue in The Daily Express.
