>In the lead up to WWII they put all their faith in the Maginot Line. This was the opposite of a reckless charge, but somehow similarly ineffective, and France fell after only six weeks.

I really should sit down and write this out at length, but in a narrow sense, the Maginot Line was entirely successful. The basic theory was to protect the Franco-German border and force the Germans to move through Belgium, which the Maginot Line proper did successfully. Step 2 was supposed to be stopping the Germans in Belgium with mobile forces, and that bit went less well for a variety of complicated reasons.

Re the bigger question, I do genuinely think this is less of a concern than it used to be. First, WWII isn't the last time we had combat experience. We're currently getting that from the Red Sea, and operating in combat-like conditions elsewhere around the world. Yes, going up against China is different from fighting the Houthis, but I think the gap between them is smaller than the one between what the British battle fleet spent the late 19th century doing and Jutland.

Second, there was a sort of mental shift on strategic issues around WWI. (Another topic I should cover at more length, and I probably should have talked about this in "fighting the last war".) The degree of casualness around a lot of really basic stuff in the RN of this era is kind of baffling, with experienced admirals making mistakes that you would need to go to the bottom half of Congress to find today. If I had to pick a start to the change at sea, it would probably be the founding of the (US) Naval War College in 1884. (The British don't seem to have set up an equivalent until 1900, and I don't think it was very prominent.) Jellicoe doesn't seem to have read Mahan until he was about to take command of the Grand Fleet, IIRC. There's other stuff, too, like much better simulation options than we used to have, and a whole infrastructure devoted to looking at this, instead of whatever officer felt like writing about it in their spare time.

> On October 7th one of the reasons things ended up as bad as they did is Hamas started by cutting communications. The Israeli military relied too much on these communications

That ought not to be possible. What I mean is that Israel, like all modern militaries, has highly sophisticated military radio systems such that you cannot shut down the radio network except by destroying all the nodes in it. You can see some of these radios advertised here:

It's said that Hamas was able to shut down the telephone-based communications the Israeli troops were using on the border. But why would they be using a system so easy to disable? No competent army would do so, and Israel has shown it has a competent army in its recent wars against Hizbollah and Iran.
