Cyber-terrorism is the new terrorism is the new communism is the new facism and so on. The military industrial complex works to serve itself, and it will invent or even create and support enemies if those enemies can be used against the public to push a bigger budget. (See Operation Gladio A and B)
The thing to realize though is that the threat is from hard to find potentially non-nationstate actors, and the threat is somewhat real, but it is hard to detect and creates a constant state of fear... which is great if you want to capitalize on that fear. To a certain extent it worked for a better good by bringing tons of money into America which along with the UK and Israel is one of the top arms suppliers to the world. (a great intro book on this subject is the updated The Shadow World: Inside the Global Arms Trade.)
My problem is that this model of fear and money has been taken to the extreme is now eroding freedoms at home, and bankrupting us. Many republicans will rant and rave about the budget, but if you ask about cutting waste, fraud, and abuse (WFA) in DoD/Pentagon they hardly ever admit such WFA exists (even though everyone actually familiar with it knows how excessive it is, especially at the Pentagon.)
The other problem is that secretly, unbeknownst to you or the general public, in the smokey closed door places in the Beltway, the strategic thinkers have been saying we are returning to a neo-cold war, and to the tripolar world, and thats the real reason for our expansionism... used a measure of containment against our future enemies, (Russia and China) in the upcoming resource wars. Iraq/Afghanistan/Libya/Syria/Somalia/Georgia/Ukraine/The Stans, all make sense if you look at it from this perspective. Don't get me started on the petroldollar and world finance schemes.
I don't know enough to quite disagree with that justification, but my problem is that if that's the real reason, the public deserves to know, but our reps and the military brass have all just held that close to their chest and we are hemorrhaging money that gets wasted and it all ends up in VA and NY, and our constitution is being undermined, while our media is captured and corruption is rampant in all three branches of government, and the surveillance state grows so the intel agencies are more and more powerful against their own people and less and less useful abroad...
All this spells disaster in my opinion.
