Against US troops in NZ

So, US Defence Secretary (and war criminal) Leon Panetta wants to station US troops in New Zealand. I have just one question to ask in response: what's in it for us? Because there doesn't actually seem to be any benefit in it for New Zealand. We get to be marked as US "territory", possibly used as a remote venue for torture or other US war crimes, and we get to have our people killed and raped by American soldiers (as happens in e.g. Okinawa). And in exchange, we get to be dragged into their wars. That sounds like a shit deal, and one no proper representative of New Zealand's interests should want any part of.
