Am I alone in feeling this way?
I tend to agree that this is a reversion to form. We have had an unprecedented period of peace, in my view, for a few reasons:
1. The construction of a system of international order.
2. Advances in technology that allowed rapid dissemination of relatively accurate information by institutions. Technology was advanced enough to make it easy to record events, but not so advanced that you could fake those recordings. And it was sufficiently expensive to disseminate information that doing so was largely the purview of institutions.
3. The technology of war was so destructive that it discouraged wars of aggression between major powers, because it destroyed the value of the territory you wanted to gain.
4. Individuals who had lived in the previous period, and took seriously concepts of public service, the preservation of international order, norms in politics, responsible journalism, and the avoidance of pyrrhic wars.
But, to bring us back to fantasy tropes for a moment, it is the doom of men that they forget. There are very few people with meaningful memories of WW2 who are alive and in a position to influence policy. Things have been really easy for a long time, and for the last 20 years or so it really didn't matter who was in power in democracies, because nobody really thought policy could have serious, existential impacts. Serious people stopped going into politics, because politics wasn't serious; and voters allowed this because they also don't take it seriously. So now political parties are populated with profoundly unserious people, and an unserious electorate elects them anyway.
As a result, the system of international order has eroded, because nobody has treated it seriously. We seem to be entering a period of interstate anarchy, which is a return to the earlier period.
News became profitable, rather than being a money-losing public service (thanks 60 Minutes
), which changed its focus. Technology advanced to a point where any idiot could fake information and disseminate it at will, with broad reach. Not being able to rely on information is also a return to the earlier period.
People have forgotten how mindlessly destructive conventional warfare is, having not waged one in almost 80 years; people actually seem to think that wars can be won relatively inexpensively. Moreover (and this is hypothesis on my part), I feel like the increased range of firepower encourages wars where a major power thinks it can wage war from a distance, without risking their own territory; this allows wars for domestic political purposes, because you don't really care how much destruction you are wreaking if you either (a) don't care to seize the territory of the nation you are bombing, or (b) don't really care what condition it is in when you get it. I also fear that our ability to construct things more quickly may make autocrats think it is no big deal to level cities they want to occupy. In any event, there is at least a perception among many that wars of aggression are worth the cost. This is also a return to the earlier period.
Unfortunately, our political institutions, and voter priorities, are still stuck in a period where democratic politics didn't really matter. And our governments have forgotten how to get anything done, because three years ago it didn't really matter. So we are ill equipped to manage the current situation. I don't know how people can look at the last three years and think that, for example, engaging in culture wars should be our top priority. But they do, and a lot of the electorate seems to agree. Why don't politicians do serious things and tell us hard truths? Because we punish them when they do.
So we are entering the FAFO phase of domestic and international politics. In democracies, either voters and politicians are going to figure out how to get serious, or they are going to cease to be functioning democracies; either by electing autocrats, or being forced by weakness to become clients of autocratic states.
Not being engaged in politics isn't an option anymore. To quote Trotsky, "You may not be interested in war, but war is interested in you."
