It may start with #landmines, but the bigger threat lies in the erosion of the laws of war.

Hear from Jody Williams, on why the recent threat of withdrawals by some European nations from the Mine Ban Treaty endangers global norms and civilian lives.

I don't think I've ever had a good shower in England. Every shower in the country seems to be broken or annoying in its own way. I don't know what it is. Every other country I've been to seems to have figured showers out.

I want to say this again, and clearly.

I spoke to three KCs, and we were formally advised by two, at Premier League sets who said FWS's case was clearly wrong, and one said not even arguable. 1/2

Something I think is often misunderstood, is that the idea that men are inherently dangerous to women is not anti-patriarchy, but in fact foundational to patriarchy... the bargain of patriarchy is: to protect them from the multitude of strange men, women need the patronage of a "trusted" man...

If adversaries use inhumane weapons, that's all the more reasons to not use them---otherwise what's the difference?

I know what landmines have done to my native country, I hope my adoptive country won't make this shameful choice

Currently, only Iran, Myanmar, North Korea, and Russia are using anti-personnel mines. #Poland, #Lithuania, #Finland, #Estonia and #Latvia should not align themselves with the military practices of these nations.

A few days ago, coming back to my hotel room in Manchester, I found a Lego piece on the floor. I kept it because you never know.

Today, my kid got a Lego set for Christmas, bought by my partner several days later near Bristol. There was one piece missing in the box: the one I had found.

This society lauded a police officer who lied and cheated and ruined lives. At last, a reckoning | George Monbiot
