We're watching the #OneLoveManchester concert and, perhaps unconventionally, I contributed a few pounds towards the UNHCR Mosul (Iraq) appeal unhcr.org then signed their #WithRefugees petition unhcr.org/refugeeday.
Worldwide more than 65 million people, greater than the population of the UK, have had their lives put on hold, been forcibly removed from the safety and security of their homes, and less than a third are being cared for by the UN in any manner.
No, this isn't me giving you a dose of perspective, I haven't got a bloody clue what's going on. It does need fixing though, and quickly. Here's a repost of my words from the week of the Manchester bombing: http://bazbt3.10centuries.org/2017/05/26/ffs-sweary
One final point, simply attempting vengeance, to kill terrorists without any other coherent strategy to stop ordinary people being turned into terrorists, will never work.
