翻訳 - 英語 -イタリア語 - I'm the decider

- "Famous" (erm) sentence by G. Bush.
- This is obviously a little game. I was wondering how best to translate it into French, knowing that "decider" does not exist in English, but "décideur" does, in French. (read: you're not "allowed" (if I may say so)) to use "décideur"... Have fun! ;)

Sono io che decido
