The arguments for and against extending RAF bombing to Syria.

For.

Britain should not “out-source” its defence to other countries.

Security, intelligence and military chiefs all say inaction is a greater risk to UK security than action.

RAF precision missiles will help target terrorists and reduce civilian casualties.

The recent UN resolution calling for member states to use all necessary means to defeat IS has provided legal authority for military strikes.

Against.

Without an agreed international strategy, military action will make matters worse.

Bombing would not add to necessary international diplomatic effort but would detract from it. Britain would have more sway diplomatically as a non-combatant.

Further military action will increase the terror threat to the UK.

The recent UN resolution does not provide legal cover for military strikes and a specific so-called Chapter VII resolution is needed.
