Indeed, but it might be many decades - once this lesson is first learned, it will take a long time to unlearn because it tends to become self-reinforcing.
To give an illustration of how long institutional memory over things like this can be:
As of when I went to primary school in Norway in the 1980's, we were still taught at length about the British blockade of Norway during the Napoleonic wars due to Denmark-Norway's entry into the war on Napoleons side and its impact on Norway (an enduring memory for many Norwegian school-children is having to learn the Norwegian epic poem "Terje Vigen" about a man evading the blockade).
Norwegian agricultural policy to this day has had a costly cross-party support for subsidies intended to provide at least a minimum of food idependence as a consequence of learning the hard way first during the Napoleonic wars with a reinforcement (though less serious) during WW2 of how important it can be.
A large part of the Norwegian negotiations for EEA entry, and Norways rejection of EU membership was centered around agricultural policy in part because of this history.
The importance of regional development and keeping agriculture alive even in regions that are really not suited to it is "baked in" to Norwegian politics in part because the subsidies means that on top of those who are about the food idependence a lot of people are financially benefiting from the continuation of those policies, or have lived shaped by it (e.g. local communities that would likely not exist if the farms had not been financially viable thanks to subsidies), so structures have been created around it that have a life of their own.
Conversely, a lot of support for the US in Europe rests on institutional memory of the Marshall Plan, with most of the generations with first hand experience of the impact now dead.
Create a replacement memory of the US becoming a hostile force, and that can easily embed itself for the same 3+ generations after the situation itself has been resolved.
Interesting; as a British person myself, we don't get taught any of that about Norway or Denmark, not even knowing that they were once joint together in a union.
I'm not surprised. From a British POV it was a relatively minor part of a much larger conflict that Britain was done with when Napoleon defeated, and Denmark-Norway was for most practical purposes treated as "just" Denmark, since Denmark was the more powerful part of the union by far.
From the Danish and Norwegian side, Britain annihilated or captured most of the Danish-Norwegian fleet because Britain expected Denmark-Norway to enter the war on Napoleons side (as a consequence, Denmark-Norway of course entered, but severely weakened), and Norway was blockaded and faced famine from 1808-1814.
After the war ended, the Norwegian mainland was handed over to Sweden (Iceland and Greenland were also Norwegian at that point, but stayed with Denmark), but Norway took advantage of the process and passed a constitution and briefly went to war against Sweden to force a better settlement, resulting in a relatively loose union. So this whole affair had a very significant effect on the formation of the Norwegian state.
