This isn't the rhetoric of a super power, more like one of a university

On the contrary, it's entirely plausible that US forces assisting with the
recovery are (1) using more communications resources than normal, and (2)
relying on infrastructure that's operating in a degraded state due to
fiber or power issues.  If so, it's entirely reasonable to put limits on
bandwidth-hungry but non-essential applications as a precautionary measure.

Here's an excerpt from http://www.nextgov.com/nextgov/ng_20110314_9111.php?oref=topnews:

   Military units operating in Japan face bandwidth shortages and
   network limitations that inhibit communications and command and
   control, Defense sources told Nextgov. Misawa Air Base, located on the
   northeast tip of Honshu, warned its personnel on a blog post Friday
   that the Defense Switched Network, which handles voice calls, was in
   backup mode and had only limited capacity, a fact confirmed by a
   Pentagon source Monday.

   The blog post added, "We have a number of connectivity issues.
   Internet has been up and down due to our connections through other
   places in Japan. For example, Yokota [Air Base] and several other
   locations are having issues because we all have power and connectivity
   issues right now."

   The Pentagon also took the extraordinary step of blocking access to a
   range of commercial websites to ensure that its networks have enough
   bandwidth to support mission-essential communications, Nextgov
   learned. This move, a military source told Nextgov, possibly indicates
   one or more undersea cables used by military networks were damaged by
   the earthquake.

Here's the problem with the logic of blocking all of the most popular
sites; they tried this from time to time in Afghanistan on the
NIPRnet. Whenever someone was unable to get to YouTube, Facebook, etc.
they, still bored and/or wasting time, simply went to some other web
site which also wasted equally as much bandwidth.
