Why are you forgetting about Cisco, Juniper (now HPE), and Arista - all of which are US companies?
Also, why is Nokia closer to the US than Ericsson?

While there's probably a little overlap in all of their product lines with Nokia (I mean Nokia makes simple ethernet switches so that carriers can buy all their gear from one vendor), most of those companies don't really compete in the same markets as Nokia
Cisco isn't selling into T-Mobile and AT&T's customer networks. Nokia isn't selling into JPMorgan's or Walmart's IP networks
Granted, I only worked as a lowly dev in the Cisco SP routing team, and I haven’t been keeping up to speed with their work.
Hence my comment :)
Nokia does in fact compete with Cisco and the others, but less so than in the past.
