(I was going to also sarcastically suggest disbanding the military. But that actually happens to sort-of work along the lines you have in mind, because we can disarm tit-for-tat along with everyone else. So what we really need is for COVID to evolve faster, until it is capable of negotiating a truce and make strategic decisions)
