While there is logic to this, it is inherently flawed, and everyone with eyes can see that. (idiom, no shade)
If Ukraine falls, we all lose.
When Palestine is razed & repaved into a footnote, we all lose.
When China, N. Korea, Russia, et al, act in tandem (more than they already are?), we all lose.
When NATO does fuck-all, and offers thoughts & prayers instead from behind a paper-thin technicality even they know it's horseshit cowardice...
When megacorps undermine political structures for their own gain, redefining their very basis on a global scale and with impunity...
When we the people as a fucking species, in the face of wanton cruelty and blatant greed, do nothing...
Well. We've already lost, eh?
Find a nice spot, shake out that folding chair, grab an ice cold beverage, and settle in for whatever the finale's gonna be. Could be impressive, could be a whimper, but it's gonna be something.
