Well Iraq was all part of the plan all along, it's not the UK's fault that America seriously bodged the security in the bits it controlled (which were admittedly a nightmare to start with). Plus Denmark has a whole 480 soldiers there, wow.

Afghanistan is another thing. It's NATO's responsibilty, any member government should be putting in as many soldiers as are needed to get the job done. Pulling out is like waving a big flag saying you don't give a damn about your military alliance, and definitely don't want help at any point in the future.
