I would start by announcing that all UK citizens operating in Iraq in support of terrorist entities, directly or indirectly, will be targetted by international forces and removed with all available force.
I think a wholse slice of humble pie needs to be taken regarding the incorrect decision to go after Assad when actually, the guys we should have been removing were the FSA.
oh, and a ruling from the international community that Geneva convention, and any form of international human rights have been removed from ISIS and their supporters including individual state legislation
