The Earth stands with ALL the trump cards.
Here we are, essentially refighting DubyaDubyaTwo (with Amerika playing the role of Kinder, Gentler Nazis) and struggling to retain the progress made since DubyaDubyaTwo as well as preserving the truly egalitarian society that grew out of the Veterans of DubyaDubyaTwo, which ultimately lead to the 60s and the attempted extension of Civil Rights to ALL people.
So much effort that could be expended on helping withstand the coming storm of Global Warming and it's side effects will be squandered by the future on Civil War 2 or Orwellian-Totalitarian Empire (the only thing that can suppress Civil War 2). On making more fuel-efficient autos, on discovering cleaner energy, on travewlling to space and mining asteriods...

It's quite clear that NONE of that is going to happen now (if these shadows remain unaltered by the future).
Gonna suck in more ways thatn one to be an Imperial Subject of Amerika in 2100.
