"Foreign Telecom Gear" really only ever seems to mean Huawei and China in these proclamations.

The fact is the majority of Telecom gear is foreign-made with regards to the US. To wit:

Alcatel-Lucent - France

Nokia - Finland

Siemens - Germany

Samsung - Korea

Fujitsu and NEC - Japan

If the US were to truly enforce a domestic US-only vendor selection it would be limited to Cienna, Cisco, Qualcomm and Motorola. And to my knowledge none of those four companies are making 5G switching gear.
