The war is on. The West, though fully aware that it is under attack, is hardly bothering to fight at all.

The BBC shows the nation a police video telling the populace what to do when the jihadis strike, while the British government continues to admit hordes of Muslims into the country.

Police have released a video telling people to “run, hide, tell” if they are caught up in a terrorist gun attack.

The four-minute video advises on how to evacuate a building, where to hide, and what information to tell police.

The video says people’s first reaction if they hear gunshots should be to run – as long as it will not put them in greater danger – and not to let others’ indecision “slow you down”.

The terror threat level in the UK is severe, meaning it is “highly likely”.

Security services have been on high alert since the attacks in Paris last month.

What should you do in an attack?

The public information film, released by the National Police Chiefs’ Council, tells people to react quickly, first by running for an exit.

“Insist others come with you, but don’t let their indecision slow you down,” the video says.

“Consider your route as you leave. Will it place you in the line of fire? Is it safer to wait for the attacker to move away before you continue?”

If it is not possible to move to safety, then people are advised to hide.

They should consider their exits and escape routes when choosing a hiding place, avoiding dead ends and bottlenecks and staying away from the door.

Mobile phones should be switched to silent and vibrate turned off, the video says, adding: “The best hiding place with protection from gunfire will have a substantial physical barrier between you and the attacker.”

Those able to evacuate should get as far away from the danger area as possible and call the police.

The film says: “When the police arrive they will be armed. The police may be unable to distinguish you from the attacker. They may treat you firmly. Do everything they tell you to do. Don’t make any sudden movements or gestures that may be perceived as a threat.”

Police said the advice has already been issued to thousands of people during security training sessions but it is now being rolled out more widely.

Mark Rowley, the country’s most senior counter-terrorism officer, said: “Everyone’s aware of the terrorist challenges across the world and there have been some awful attacks. It’s our view that this advice should be rolled out to the public so in the tragic event that anyone gets caught up in a rolling firearms or weapons attack they are better informed and better advised to protect themselves.”

As so often, Mark Steyn writes good sense about the war between Islam and the West – a war the West is losing.

Many of the Republican candidates sound too anxious to repeat the mistakes of the past 14 years. Lindsey Graham is perhaps the most absurd exemplar: a man who favors massive military deployments around the planet, but open borders at home. And so he wound up, even as he was threatening to loose tens of thousands of soldiers upon their lands, apologizing to the Muslim world because Donald Trump is a big meanie. Perhaps Graham would be more amenable to sanity if we couched it in progressive terms: The “safe space” ought to be western civilization – which means that accelerating Muslim immigration into the west will only make our cities an ever bigger unsafe space for ISIS and others to exploit. The problem in San Bernardino is not just the “radicalized” Syed and Tashfeen, but the semi-radicalized revert neighbor and the hemi-semi-radicalized dad who told Syed to lighten up about the Jews because Israel wouldn’t be around in another two years and the wives procured through Green Card fraud and the locals cowed by political correctness into looking the other way as Muslims build pipe bombs in the garage. None of this is in the national interest of the American people. But Fieldmarshal Graham wants a blitzkrieg overseas and a home front that allows US citizens and their mail-order brides to choose what side of the war they want to be on.

By the way, what does “vetting” even mean? In a multiculti world, you can believe everything Caliph al-Baghdadi does – that infidels are unclean, that women are the property of men and should be forbidden to feel sunlight on their faces, that homosexuals should be tossed off the roofs of buildings, that apostasy should be punishable by death, that Sharia should be introduced in western nations, and that the Islamic crescent should one day fly from the White House and Buckingham Palace and the Élysée and St Peter’s. And Hillary Clinton and Bernie Sanders have no problem with that, as long as you don’t actually build a pipe bomb or blow up an airliner.

So there is no actual way of “vetting” anybody until after you’ve left a big pile of body parts all over the floor. …

I like western civilization. I regard Common Law as superior to Sharia, so I would rather people who wish to live under Sharia remained in the many countries where it already operates, rather than adding Austria and Ireland and Denmark to the list.

A schizophrenic strategy of ineffectual war overseas and celebrating one’s tolerance of the avowedly intolerant at home will ensure we lose.
