Even if the executive order had been a recapitulation of CISPA, CISPA has nothing at all to do with PIPA and SOPA.
But it most probably isn't a recapitulation of CISPA; it is simply a series of directives on how the federal government should secure their own networks.
Executive orders are a clear signal, that a President is unable to get a majority of delegates behind a specific agenda point. We have seen over and over again that under the cover of good intentions bad things are sneaked upon the public - and presidential orders are the ideal tool to accomplish this.
I can completely understand that he is trying to circumvent the House on partisan issues (e.g. welfare, health care, etc) and avoiding compromises on his key agenda points.
But if he is unable to create consent on a deeply hawk'ish issue such as defense, then there is something seriously wrong - either with the president or with the proposal. Considering that there he is still part of an active political process - even across party lines (e.g. fiscal cliff) - the problem is not with the president - but apparently with the proposal.
Not saying that Hagel is such an outliner, but it is easy to nominate a fringe candidate of the other party and then pointing fingers when his own party does not support his views. Of cause something as sneaky as that would be unimaginable in real-world politics, and I am probably just watching too much House of Cards.
Afaik only some leaked drafts have been circulating around and speculations have been going wild. After the PIPA/SOPA backslash are you honestly expecting "good intentions" when the a president is trying to get a very similar subject "solved" by circumventing public discourse?
