I accidentally deleted a bit if my last post. Here goes again:

Talk of self-defence in this context is misleading. The violence is self-defeating to ordinary people on both sides. It serves to ensure that the violence by the other side continues. I suppose it is possible that that is not the intended outcome, but the longer this process continues the less likely that seems likely to be true.

That is particularly true when it comes to acts which appear deliberately intended to ensure that a ceasefire breach is escalated.

Non-violent resistance by Palestinians can be a real threat to the status quo, which is why those who attempt to act in this way, including Israeli supporters, meet a brutal response.

It does not seem like a matter of disproportion, but of calculation.
