With large numbers of police moved to high profile public events such as the footy in Cardiff and the gig in Manchester, and seeing how successful the incident in London involving an SUV driven across one of the bridges into pedestrians, is anyone surprised that a similar attack has taken place?
Any terrorist with an ounce of sense will repeat a previously successful attack where the police presence is likely to be at a relatively light level, using a proven process, i.e. using a vehicle as a weapon; simple and very, very effective.
DAESH will claim their soldiers were responsible, and those responsible will probably claim to be fighting against the evil Western kufir, which is again highly predictable.
I see little difference to the IRA planting bombs in concrete rubbish bins a couple of decades ago, only the ideology has changed, and even then not by much; both are groups seeking to impose their ideology on the majority by the use of force, with their religion used as an excuse.
The more things change, the more they stay the same.
Or as they say in France: Plus ça change, plus c’est la même chose.
