"Cannot"? Why wouldn't it just require a much bigger effort?
I've been flabbergasted by the lack of wartime thinking this whole time in the US. We know how to mobilize things and build logistical supply chains, why can't we apply that to a in-country medical battle?
Not only did the US governments (at all levels) demonstrate incompetence early, we've now given up on even trying to be competent.
That bodes poorly for future events.
If you're a person who can work from home and isolate, or just someone who's not scared because you think your personal odds are good, then it burning through the rest of population faster is better than it burning through more slowly, which is the best most of the country had gotten through their restrictions. But wow... what a low standard for our country.
