If you go to Washington DC and go to the Watergate Hotel, right across the street and not on Embassy Row is the massive Saudi Embassy, reminding everyone who comes in over Teddy Roosevelt Bridge who runs barter town.
Embassy size doesn’t correlate with power. This is easy to observe in various European countries, where the Russians managed to hold on to their huge Soviet-era embassies, even though their contemporary influence is far lower.
There is a really interesting dynamic where the Saudis have basically pushed the line of thinking that they have a special relationship with us going back to WWII or WWI. I generally am a bit skeptical of Cato Institute but they had a great podcast with Prof Robert Vitalis about this that shed a ton of light on exactly this question for me.
