If anything can be described as "bonkers" it's the plot of The Cassandra Crossing, a film which I love in a guilty-pleasure sort of way. Can someone explain, since the screenplay never bothers to, why

(1) the US military is conducting bio-weapons research in the Geneva WHO headquarters, of all places;
