Eternal punishment in the Netherlands? (9)

I believe the answer is:

damnation

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

'eternal punishment' is the definition.
(I've seen this before)

'in the netherlands?' is the wordplay.
'in the' becomes 'dam' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'netherlands?' becomes 'nation' (netherlands is a kind of nation).
'dam'+'nation'='DAMNATION'

Can you help me to learn more?

(Other definitions for damnation that I've seen before include "Curse" , "Infernal punishment" , "27 [HELL]" , "Mild oath" , "Eternal punishment" .)

I've seen this clue in The Times, The Sun and The Telegraph.
