You seem to have a binary view - the option opposed to doing nothing, is not invading - that's just a stupid straw man argument.
I don't have a solution and don't claim to - but I'm not going to hold up as a hero a regime that cuts off the hands and feet of robbers.
The Middle East seems to be choca block full of religious looneys who would happily kill you and I just because we don't share the same beliefs. There is no easy answer to that - rest assured though, rolling over like a puppy and pissing all over yourself isn't going to cut it either .
However, people who have no human rights, are murdered and tortured, won't suddenly get equality and fairness if we just sit around and hope ( and look the other way)
On another note, news is about the exception - we stop paying attention to 100 people killed in a market bombing, but we pay attention when it happens in a secular western country?
(Just secretly I'm coming to blame Turkey and Saudi Arabia the most)
