Unfortunately, after eight years of Obama, there are leaky sieves throughout all the Western intelligence agencies. This never happened under Bush and Cheney, who both ran a tight ship. 

We need to go back to that level of security and also to reinstate the Rendition programme, which was working very well and stopped all attacks post 9/11. It was only when Obama stopped Rendition and drew down troops from Iraq that the West started to get hit with one attack after another.
