Whilst I agree with every point raised by Cronius, there is a part of me that thinks, why bloody us again? Our defence industry has made billions selling top grade military kit to the Saudis, UAE, Qatar etc.
There's more than enough there for those Arabs to get off their arses and take care of the problem the whole region is facing.
And has anyone heard one squeak of condemnation from any Muslim Authority here in the UK? I asked a couple of Asian friends, "Why the silence?" The reply was an eye opener...."They (ISIS) are already amongst us.....they are actively recruiting our young men....they know where we live! That's why we're saying nowt!"
And of course, there are a good few hundred Brits out there in the ISIS ranks that will be looking to come home sometime.
Deal with it now, even if that means boots on the ground as part of a UN backed coalition. Otherwise,the consequences could be horrendous.
