Well you could say same about Canonical not being able to make a deal with Chinas largest smartphone supplier and focusing on world largest smartphone market.

Jolla might say "we will target on US market later on", but what they really are saying is that they might someday enter to the market. It just seems so obvious on how they talk about their market focus. China->Asia-->Europe-----> North America.

US is pretty much lost market with the current juggernauts and operators having full control on the puppet show. If Jolla somehow makes it big someday they might go for it, but i don't see it happening otherwise.
