The UK Home Office apparently will suppress a recent report about sources of funding for terrorism. You can read about it here:
To me this sounds exactly like what the US did with the suppressed 28 pages of the 9/11 report and other revelations of such funding sources. You can read about them here:
The FACTS (if we can agree on the facts) suggest that most terror is funded by nation-states (such as the US, UK, Israel, and Saudi Arabia), tolerated by them, or carried out by persons trained by them.
It therefore makes no sense at all to believe that more spying and bombing will bring an end to terror attacks. None at all.
