Yes chemical weapons are wrong but as said in previous replys it's not our business to get involved we are a tiny island who have already have stuck our noses into too many countries internal affairs. No one in Syria will thank us for getting involved or want us involved.
It's going to boil down to Russia & America whats happens now anyway so why do we need to even get involved Britain needs to stop thinking its a world power and accept we are just a little island & little island that is in debt up to our eye balls !
