Local amateur historian and occasional beloved family member Paul Poppavich vehemently dismisses news of fascism’s rising international tide, despite an encyclopedic knowledge of World War II history.
So I started listening to a US civil war podcast, The Civil War 1861-1865: A History Podcast, and I have to say that I find the most interesting parts to be the parts about the politics of everything.
The really quick, really accessible version is the Extra Credits videos, though understand that they simplified a lot of things, and made some mistakes (which they admit to in a follow-up video).
The Great War YouTube channel also covers some of the same ground in an accessible but more rigorous manner, though I don't remember them going over all the "clash of empires" background stuff.
On the far other end, I liked the book The War That Ended Peace by Margaret MacMillan. It's a dense tome, but it's chock full of details.
