I think what he says is true. It may not be tomorrow, but it will come if ignored. These people have already threatened the UK and the White House. They don't care who they kill, so long as it's non-Muslims and they can continue to build their caliphate.

The West is embroiled in a generational struggle against a poisonous brand of Islamic extremism that will bring terror to the streets of Britain unless urgent action is taken to defeat it, David Cameron warns today.

Writing in The Sunday Telegraph, the Prime Minister says the world cannot turn a blind eye to the creation of an extremist caliphate in the heart of Iraq.

Warning that Islamic State fighters already control thousands of square miles of territory, Mr Cameron says that if these “warped and barbaric” extremists are not dealt with now, they will create a “terrorist state” on the shores of the Mediterranean.

He warns that Britain will have to use its “military prowess” to help defeat “this exceptionally dangerous” movement, or else terrorists with “murderous intent” will target people in Britain.

The Prime Minister says he fears the struggle will last “the rest of my political lifetime”.

“The creation of an extremist caliphate in the heart of Iraq and extending into Syria is not a problem miles away from home. Nor is it a problem that should be defined by a war 10 years ago. It is our concern here and now,” he says.

“Because if we do not act to stem the onslaught of this exceptionally dangerous terrorist movement, it will only grow stronger until it can target us on the streets of Britain. We already know that it has the murderous intent.”

In his article, Mr Cameron says Britain and the West need a firm security response to the crisis in Iraq and that fighters from Islamic State of Iraq and the Levant (Isil) cannot simply be removed by air strikes alone.
