Firstly I would offer my condolences to the family of David Haines. The British aid worker savagely murdered by Isis.
How do you stop the spread of what can only be described as a cancer to everyone that has the misfortune of being ruled by the Islamic state.
A few air strikes won't work.
The civilised part of every nation on earth must have a overwhelming response to iradicate the spread of this disease.
And if that means boots on the ground then so be it.
Just a thought for all the anti war protesters.
Go and talk to Isis and see how far you get.
You will be begging for boots on the ground before your head ends up next to your boots.
