Should the Yanks attack Syria?

President Assad has deliberately bombed civilians - women and children - and used sarin gas which is a big no, no. The UN is supposed to fix this sort of stuff but its a lame duck organisation. So, US president Obama and his mates are on the verge of launching an all out attack on Syria. I really don't know how I feel about this. If Iran, Russia and China get drawn into it all hell could break loose. Any thoughts?
