This is the weekend I get my wood in (i.e. have pellets delivered) so I'm thinking of chillier days even though it's 70° outside.

A generation later, Donald Trump’s war on Iran has apparently delivered it for him: **(SEMI-)CROSSPOST: RICK PERLSTEIN: Bush’s War Is Finally Over: Al Qaeda Has Won** & U.S. airstrikes are apparently now being launched off of carriers supplied from Diego Garcia 3000 miles away from Tehran, and from Muwaffaq Salti in Jordan 900 miles from Tehran… 1/
