Radio reports suggest that the US has "strongly recommended" that Pakistan provide all required cooperation should it be required. This provides the gateway to Afghanistan...but may have the unfortunate consequence of drawing in India...etc, etc...if a world war can be born of a single assassination, what will become of this should someone be identified as responsible? Will ethical concerns about striking a group of likely targets be aired, or will the understandable US bloodlust be ignored until all the information needed is in place? Sad times indeed.
