@ YoungMaf - Not sure why you think any of the "anti-war brigade" on this site, as you characterise them, would object very strongly to what was done in Libya.
Following reports of the slaughters of the Gaddafi regime, the UN passed several resolutions, condemning the actions of the regime and freezing their assets, as well as referrring Gaddafi to the International Criminal Court.
When Benghazi was threatened with heavy weaponry, the UN passed a "no- fly" resolution, and authorised the use of all necessary force to defend civilians.The UK, France and the US were all instrumental in enforcing the no fly zone. and then maintaining it. So, limited military intervention, sanctioned by the UN, supported by Libyans and the Arab League, for a humanitarian cause - I think you need to stop conflating all anti-war protesters and resolute pacifists, steadfastly opposed to any sort of military response.
All of this action represented limited military intervention by the UK and others, and was both justified and affordable, both in terms of logistics and economics.
So, it wasnt a war, nor did we commit to boots on the ground (although there were probably special forces and advisers)- why do you imagine anyone here would object, or "bask in their own self-satisfaction", as you so poetically put it?
