They can say that it shows the threat that the US has from other countries on a hacking front

There have been attacks on the US government IT infrastructure. Stolen designs and files from military contractors. Attacks on energy and distribution systems. Attacks on the banking system.

On the grand hierarchy of attacks, this is really, really low. I mean, given the severity and regularity of attacks against things that really, really matter, no the US certainly didn't need this to justify anything. The concern is very real, and significantly more important than some Sony Entertainment emails or movie leaks.
