we have not yet found a way to frame it in a way convincing enough for everyone to come together against it.
You're absolutely right about this. And come to think of it, it's even questionable if it's even the right way to frame it in war-like terms, as in "us against it"... I think that the first step should be a major investment in education, build up some scientific literacy... Not the kind of education that rewards students who are best at reproducing the facts and information the state feeds their minds, but the kind that teaches students to think for themselves...
Having said that, as I'm not one to dismiss the virus as some kind of conspiracy, governments should try all they can to aide in combating the spread of it. That's exactly the opposite of what Trump did in America by not taking the threat seriously.
