with any Somali vessel venturing outside their territorial waters without specific prior notification
Who should they notify - the ones that aren't pirates? Have you any idea how big the area is that has to be patrolled and policed? The number of ships / boats / fishing vessels etc involved?
The Somali coastguard / government / navy perhaps - you know - the ones that don't actually exist? The UN? How do they notify? How is it recorded? How is it checked & verified?
As much as it sounds nice to go bomb some pirates you aren't thinking through how complex that is and how unappealing the 'collateral damage' (innocent human deaths) that would occur in an area which is in chaos with no functioning government.
And I guess you'll soon moan if the prices of your commodities go up too.
