I wonder how acceptable it would be to swap nurse/pandemic/get sick with soldier/war/get shot, or with fireman/forest fire/get burned. Some professions have different risk profiles than others.
The right thing to do is obviously to reopen the schools, but the virus has to be under control first.
Feeling like this is not a war is a big reason we have all had to endure so much risk. We have been unwilling to make the tough decisions, unwilling to move ahead with imperfect information, unwilling to sacrifice trivial liberty to do what is clearly safer for our fellow humans.
I think the war analogy is useful, in that the Federal government should be able to have access to higher authority to execute on strategies quickly. I mean, we use the "War on ____" analogy enough, this pandemic is certainly more fitting than most of those issues.
I also don't think there is any new law that would need to be enacted to grant additional authority to the executive branch. I agree, they had all the tools in the toolbox before and after the pandemic hit us. I didn't mean to seem to advocate that the executive needed more authority than they already posses, just that the authority they already posses is higher than we would normally be comfortable with without a crisis.
I mostly meant that the war analogy is useful from a public perspective, because there are a lot of people who don't think in shades of grey, it's either war or peace, and to get them to do or accept what needs to be done, they need to be motivated.
Getting transmission rates and new cases right down quickly requires sweeping, war-like measures and mindset. This failed because no-one has been willing to take them, and a significant portion of the public thinks that individual freedoms trump everything else.
I don't see a problem with the term.
Edit: I'm puzzled by some of the replies and ideas on what being at war means.
It does mean solidarity, collaboration, cooperation, including extensive international collaboration. A prime example is WWII.
It think it is not unreasonable to call covid-19 an enemy that must be defeated if that focuses minds. It is in fact very common to use war-like analogies in campaigns against diseases. That includes smallpox and polio.
In your response to your edit I think you have a very rosy view of war. WW2 involved setting cities on fire, locking up ethnic minorities because of their ancestry, and forcing removal of people from one country on the other based on their ethnicity and language. And all of that was on the part of the U.S.
Warning, generalizations ahead: Unfortunately you really can't take coordinated, collective political action on anything in the USA unless you pretend it's a "war". That's why we name things like "War on Drugs" and "War on Terror". The only way you can even hope to convince Americans to put their political team aside and get behind an idea is to convince them that they are fighting a war against some kind of enemy. So I can understand the attempt to label this a war--the intentions are good.
Everything you mention should exist even without a war, it is just the foundation of a civilised society. Rule of law by definition requires us to discipline ourselves. There are plenty of situations besides playing soldier where we work with others towards a common great goal.
Seeing everything as a war just reinforces black-and-white thinking and seeing everything as a zero-sum game, when the times call for solidarity and international collaboration. We need the opposite of the knee jerk phony patriotism and nationalism that get exacerbated by all this tough talking. It is a natural disaster, not a war.
We have analogies that work. We eradicated smallpox and went almost there with polio. There is no need to find ennemies.
