what might happen if for instance, over the next five years, all defense budgets were directed into clean energy and energy storage development
That reminds me of an image I saw the other day for the US military budget last year. Don't know how accurate it is, but it does go with some things I've heard before, so I saved it.
What the countries of the world could actually do if they would stop all this military spending and fighting.
Accurate or not, it represents what the real possibilities might look like. It is insanity that "we the people" keep voting these jokers in, rather than organizing ourselves.
