Apologies as I can't remember who posted it but the article which fully explained why and how we could be heading towards WW3 was absolutely fascinating - and terrifying in equal measure.
It didn't pull any punches and stated quite clearly that it was the pull back by the Obama administration which gas basically set up the existing global climate as the two biggest threats (Russia & China) now feel they can push further and harder, believing that the US will remain America First.
The fact we (the UK) are also looking to go it alone via Brexit upsets and worries me even more now I've read that. I was a very strong Remainer for different reasons (freedom to travel & study for my DC mainly - plus, I'm a 'liberal leftie' and strongly believe we're better together) but I think if I'd read an article like this before the referendum, I would have been much more passionate about the potential fallout of of a Leave vote.
It's pretty depressing really 
I have however just watched all the SuperBowl ads which made me smile a little. Couldn't work out what a lot of them had to do with what they were flogging - particularly the timber one or was it saying that even though the wall might get built, they'll happily employ people who enter the country illegally??! Anyways, clear messaging from most of those companies that Americans are all one people regardless of race, colour or creed..
