The UK Parliament clearly believes it is making the world a safer place by deciding to authorise air strikes in Syria by UK aircraft. Therefore, under a global system relating to the World Balance Sheet, the costs of those air strikes, in terms of the equipment, staff and logistics etc, should be borne by those who are being made safe. This should also include any damage to infrastructure, and some measure of non-combatants’ deaths, eg in terms of the loss of productive and valued members of the Syrian public.
If global welfare insurance existed, then it would be easier to charge the costs of security to those whose security and safety is being maintained, because their global welfare fund would cover the costs. To the extent that this is citizens of Syria, then a bill should be sent to the Syrian Government, who have failed to provide that safety so far. To the extent that it is people in other countries, including Western nations, then they should also receive a bill.
The United Nations could act as debt collector. And if Governments like the Syrian one (which would have by far the largest bill) can’t pay, then assets of value in the World Balance sheet (eg sustainably managed land) could be seized by the UN in lieu of payment).
