I don't beleive that it will lead to a 'shorter fuse'. The object of the ransoming/kidnappings is money, not terror. If the pirates know that they will more likely end up getting killed than getting rich they will be dis-incentivized from trying to pick off more ships.
Short term, there might be some retaliation, long term it's a start towards curtailing these guys.
Next step is to blast the 'mother ships' with a missile, stranding the speedboats in international waters.
