Well the walls have been working fantastically well for Israel. Suicide bombings just don't really happen anymore. Yeah sure, the knifings have been going on, but those kill a lot less people.
15 years ago there used to be a bombing every week.
The suicide bombings only came after attacks by Israel, each one was a response for an attack by Israel, for example attacking apartment buildings with helicopter gunships. That's important to remember - they have a context.
Yes the wall is working well for Israel, it's annexed more of the West Bank by default, and is disrupting the lives of Palestinians massively, and also the migration of wildlife.
There's been quite a lot of violence lately, death toll is still pretty high since late 2015.
