Well the UK & USA love a conflict, I cannot in my lifetime remember a year when we wasn't fighting somewhere in the world. So we'll probably go in regardless of what evidence is produced, whether we should or not is difficult to say, when you see dead children on mass lying in the street it's difficult to say we should stay out of it. But the innocent and children will always be caught up in wars, both the UK & USA should know this as over the years they've killed plenty of innocent people, which is normally reported as being caught up in the crossfire and being no more than an accident.
I think it is now time for the UK to take a step back from other countries problems after all it has nothing to do with us as a country. Secondly this country is making many of the forces redundant, through cut backs, we've got people out in Afghanistan, Gibraltar, Falklands and other distant places, we've got little in terms of warships, I'm not sure about the state of the air force apart from us having a red arrows display team

so I'm guessing that as a country we're pretty exposed defense wise currently.
I also believe that if intervention into another country's civil war zone for humanitarian reasons is unavoidable then it should only be done under the banner of the United Nations and not another country trying to force it's will onto others.
My other main issue is, it's easy for our politicians from both the UK & USA to send youngsters aged 18-20 into war zones and then declare them 'heroes' when they come back having lost limbs or in body bags, but it is never the politician who has lost an arm or his legs....
