Did the nerve agent VX kill Kim Jong Nam?

Last night Malaysian authorities announced that they identified the nerve agent VX taken off the face of Kim Jong Nam, who was murdered on February 13 at Kuala Lumpur International Airport. As the History Channel video above indicates, nerve agents are potent acetylcholinesterase inhibitors that utilize the same mechanism as organophosphate insecticides such as parathion. Conceptually, the effect of VX exposure is simple: wherever in the body acetylcholine acts as a neurotransmitter, nerve agents cause unregulated, chaotic activity. There are generally 3 such sites: muscarinic sites: connections between nerves and secretory glands and smooth muscle nicotinic sites: neuromuscular junctions central sites: in the cerebrum and brainstem The effects of nerve agents on these sites are predictable: muscarinic: massive respiratory secretions, bronchospasm, severe diaphoresis, vomiting, diarrhea, meiosis, and lacrimation nicotinic: voluntary muscle fasciculation and spasm, followed by fatigue and flaccidity central: seizures, central apnea Victims exposed to nerve agents die of respiratory failure, due to a triple-whammy: airway obstruction and bronchospasm, dysfunction of voluntary muscles of respiration, and loss of central drive to breathe. With 3 separate types of effects, there are fittingly 3 antidotes: muscarinic effects: atropine nicotinic effects: pralidoxime (2-PAM) central effects: benzodiazepines such as diazepam Despite the announcement that VX was identified...
