What ridiculous nonsense that we 'need' Iraq and Afghanistan'!!!
Yes our purpose is to do our job, but we don't need to constantly have a war to exist - that would truly make us a self licking lollipop, always looking for a fight to prove we're needed.
Our purpose is to defend the UK, secondarily to that we action UK foreign policy.
What we need is to be able to do the first effectively and without doubt.
I think there is no place in the modern military for anyone who could be so stupid as to say 'we need a war, it's our job' , bloody cretin.
