I'm not sure if other countries place us on a pedestal like weebs do Glorious Nippon, but I'm sure they don't really have to because American media is so spread out globally that it's just normal and probably just whatever to most people living outside the States. I watched a J-drama and they sang Whitney Houston, whereas I doubt most (99%) of westerners know who the fuck Utada Hikaru is. Because over here, Japan feels like a foreign place and isn't dominant in the culture. It doesn't help that a lot of weeb circles are circle jerk-y as fuck. I'm pretty sure people obsessing about American culture probably happens, probably more than with weebs, too. Glorifying that place that isn't home is a part of the human condition.
Also, given that most American imports tend to be really big stuff like movies, I'm pretty sure the westaboo doesn't give a fuck about western cartoons like a weeb does with JP toons. I mean, The Simpsons doesn't even air in Japan, for instance. I'm pretty sure most westaboos are more into American movies or American video games more than our cartoons. Westaboo's like Kojima are a good example of this. When you consider that, westaboo-ism is probably common, at least in places like Japan.
It also helps that weeaboos are a global phenomenon, so not just America is on that Pocky and Ramu Botoru steez. As we've seen with the Japanese mascot discussion, Japan has always had a keen talent for creating memorable characters and stuff that takes over people's souls, even as far as their own folk tales. So a lot of people globally, especially the nerds, naturally get that Weeb Infection, especially in places like France.
