In what way was Germany "bombed into the stone age" in the First World War?
Perhaps a confusion for the Second World War? In WWI most bomber planes weren't advanced enough for long-distance bombing on a large scale. German largely fought its war elsewhere and other countries had the pleasure of being turned into moonscapes.
The penalties of the Treaty of Versaille weren't sufficient to prevent Germany building a highly advanced industrial-military complex within a mere 20 years, so "bombed back to the stone age" is particularly inapt.
After WW1, Germany was overt about the fact it was building an empire, intended to compete with the British empire aka largest empire the world has ever known.
The leadership types got enough buy-in from the people buying bread with wheelbarrows of money to be able to mobilise an army, invade much of Europe, carry off The Wrong Sorts to concentration camps, and have enthusiastic volunteers dobbing in their neighbours to ensure everyone toed the line.
By "more of the same" I didn't mean they intended to be in the trenches being killed, but there were certainly enough people in favour of solving their own unhappiness by attacking other people, and other countries, to enable it.
So no, not identically the same, but certainly more of a medicine of a very similar kind to the one which had failed the previous time round. This is what I mean by the country not having changed this aspect of itself after WWI.
