The entire thing is a fairly transparent attempt to gin up some anti-russian sentiment in the wake of a growing presidential scandal under active investigation that keeps turning up damning evidence. At best it pulls the administration out of the fire for a few days but frankly all its doing is insisting the US is open for business until we find a big enough bus to throw you under for our own political gain.

Its difficult to cast an outright ban on import as anything less than telecom players waving their hands and crying red-scare to an audience of congressmen that are either old enough to remember duck-and-cover drills or ancient enough to have actually participated in some of the clandestine blacklisting and CIA funded government overthrow in central America.
