Well the jordanian hangmen are going to be busying if they carry out their threat to fastrack the executions of ISIS prisoners around 200 apparently , one of whom is a woman.
A nuke isn't the answer, a nuclear explosion anywhere in the world, isn't good for anyone, even a small tactical nuke. However, if the civilised countries in the world actually want to win this war, they are going to need to be realistic about how to win it. To win you will need at least half a million or more troops in the middle east for years, similar to the amounts we had permanently in germany facing off against the soviets, you will need different rules of engagement for our war fighting resources, which will mean there will have to be an acceptance of mass civilian casualties, You also need ,to insert private contractors, into the area, to do extremely dirty work, psychopaths leading bands of cuthroats and sadists, you would need to stop the press embedding with the armed forces, as routine, and have media blackouts, as I don't think the people of the US and the UK could take what would have to be done in the middle east.Think of the pictures of dresden for shocking reference, yes it has come to that.
Finally youwould need to remove President Obama and Prime Minister cameron, and put in place leaders who can come to an agreement with Putin the russians , and the chinese, north korea, to at the least stay neutral and not kick off in their respective areas of influence, which will mean a humiliating climbdown on our part, And ideally supply man power to the middle east ,as obviously it will be in their interest to have a final solution for the problem of radical islam.
All this of course could have been avoided,if we had avoided Bush's decisions to remove saddam, and the later insanity which Obama presided over called the 'arab spring', . The middle east,needs dictators and plenty of torture chambers to keep the islamic tribes in check.
So basically unless we do the steps I have laid out, in the end this barbarism will knock on our doors. This is what comes when we have to choose between naive spineless fools for leaders.
