In your opinion.
As far as I am concerned if national security is a reason Cameron uses to hector people to stay in, then events like today only serve to demonstrate that it is an empty promise.
If you think that EU expansionism to the borders of Syria, Iraq and Iran would have no bearing on our national security then personally you are deluded.
That does not even recognise the possible threats by opening up free movement to Turkey before it is formally accepted in the club.
I also understand that the metro bombed today is one of 2 used to access the EU quarter.............on plenty of measures this attack has lots to do with the EU.
You are twisting the story to your own agenda. That is typical of the EU debate. Were terrorists targeting the EU? Possibly. Does membership of the EU make us a terrorist target? Possibly. Is membership of the EU and access to shared security going to make us safer? Possibly. Would London still be a target outside the EU? Possibly.
Possibly.
But you dress it up as definitely.
