Here's a question for all the American charedim, or charedi wannabees, who have made aliyah: Name five recent or current American charedi great Torah scholars. They can be charedi gedolim, but they don't have to be. There's plenty to choose from. Rav Shmuel Kamenetzky, Rav Leff, the Novominsker Rebbe, Rav Yitzchok Sheiner, Rav Aharon Feldman. Or, you can go for the local younger generation in Beit Shemesh: Rav Chaim Malinowitz, Rav Elimelech Kornfeld. And in terms of recently deceased, there's also plenty of examples; Rav Nosson Tzvi Finkel, etc. Think of anyone that you want.
