said by AnonFTW :So the US government is protecting revenue streams for other countries' companies? I think you're reading too much into this.
Regardless, who do you think it is that supplies those companies with gear? Qualcomm, Ericcson, Nortel, Alcatel-Lucent, etc. The government is trying to protect the $100B+ annual revenue of those companies. They don't want ZTE and Huewai entering the market and undercutting the domestic suppliers, which is exactly what would happen.
