Hands Up Dutchboy! expatica.com reveals that

"The Dutch parliament was shocked by a US legislative proposal giving an official green light to a US invasion of the Netherlands should it be deemed necessary to free US citizens from the International Criminal Court in The Hague. A Volkskrant newspaper report said almost all Dutch political parties believed the US proposal undermined the authority of the court, which will officially become active from 1 July. ...

Despite their opposition though, the parliament did not consider it a serious scenario that the US would make use of the legislation and a Foreign Affairs Ministry spokesman also said it was unlikely that US warships would be positioned off the Scheveningen coast."

Well I guess there is one sure way to find out. On the other hand, if they dislike suspense, they could always kick out their disreputable guests. By the way, the court opens for business on July 1, 2002.
