The IRA was mentioned, and I always think it's interesting to juxtapose it with Hamas.
Hamas arguably intends to use somewhat similar tactics to achieve a political goal, but there are problems. The IRA was mostly looking for independence, whereas, Hamas is mostly looking to destroy Israel. The one is much easier to provoke than the other.
The IRA famously demonstrated capability to threaten British leaders, while not actually acting on it.
Hamas, OTOH, given its goal, has to take really stupid actions(like shooting kids at a music festival), totally destroying whatever moral authority they have across the entirety of the world, in hopes that the at this point super unreasonable view that Israeli Jews aren't native is correct, and in the face of such pressure, will simply pack up and go back to Europe.
That fundamental goal, and the fundamental presumptions Hamas makes about Israel, are both just really stupid, but I wouldn't expect them to change it. At some point, I have to wonder why the historic leftist attachment to these guys doesn't wane, they're very clearly just belligerent fools with no real hope of success. Just gonna march from disaster to disaster.
