Militarism as a key cultural value means Israeli Jews are compelled to participate in war crimes, and compelled to support really stupid strategy. It's very difficult for them to articulate non-military strategies. Former generals often go into politics, so politicians lack any larger perspective too (Rabin being an exception).
For the right, this isn't a problem. For the left, it means they will say they support peace even as they personally destroy any chance of that happening.
