The World reels from yet another Jihadi Daesh outrage - this time in Barcelona, but no different to Paris, Berlin, Brussels, London, Manchester or so many other places. Our hearts go out to the Spanish and to the bereaved and injured. We grieve, and we are resolute in never giving in to terrorism, and carrying on with our everyday lives as a kind of mark of defiance. All of those things are good and true and noble. But the trouble is that they just don’t work. No matter how many candlelight vigils, streets strewn with flowers we see, these evil people see a soft West, and a West which can be defeated by their wicked and violent tactics.

These people understand only one thing – strength. That has been proved throughout Iraq where Daesh are now virtually destroyed, and very nearly in Syria too. The Jihadi Caliphate was destroyed there by force of arms, by sheer power. Yet unless we also destroy the ideology, and cut off their source of funding, this multi-headed hydra will just go to ground under the sand, and will without doubt reappear in all its ugliness elsewhere in the Middle East or Africa, and most certainly in yet more high streets in our Western cities.

We need to deal with their ideology at grass roots level.  And we must be clear and firm. People who are returning from Iraq and Syria, for example, must be carefully quizzed by MI5. And if it turns out that they have been fighting for ISIS, they must either be thrown out of our country, or at very least have their passports removed and after due process of law they must be thrown into prison. Those people who the security forces know to be suspect must be investigated, irrespective of their bogus human rights claims; those who are in prison should be sent back to wherever they came from irrespective of the regime in their home country.

And we must strengthen our delicate western liberal consciences over such things as surveillance. I don’t mind being watched, and anyone hacking into my phone or computer would find nothing more interesting than a shopping list. We must be ready to lay the blame where it lies, and be outspoken and clear about it.

I was horrified by Sarah Champion being thrown out of the Shadow Cabinet because she identified (perfectly correctly) that it is Pakistani gangs who are raping and selling white girls across much of England, including in her own constituency. The political correctness of avoiding calling them Pakistani, has overcome anything approaching common sense. If they are Pakistani people committing these crimes, then we should say so. That implies no disrespect for the Pakistani community in general; quite the contrary. Just as we would not mind if it was said that ‘It was a white man who robbed the bank’- they should be quite happy to highlight that these criminals are of Pakistani origin, but are quite different to the hundreds of thousands of wholly law abiding, decent Pakistani people, many of whom I was brought up alongside.

Walking on politically correct egg-shells will not prevent another Barcelona, or Manchester. Locking these bad people up, or throwing them out of the country, may well help towards it, even if it bruises a few of our delicate Western sensibilities in doing so.
