Honestly, digging up a random article from Christian Science Monitor seems more like an attempt at stirring up emotions against the the right than anything else. Most of the responses here are pretty much "the right sucks," "America sucks," and "Christians suck" (pretty progressive judging an entire group/nation/religion based on a single obscure article) rather than talking about the game itself.
Everyone raise your hand if you've even heard of CSM! Those of you with your hand raised, how many of you take it's influence seriously? It's no TIME or Times, it's Christian mother f#$*ing Science Monitor!
Personally I'd assume any American would rather defend their country from an immediate threat than attack a vague foreign one. When I first watched the trailer my mind went immediately to Freedom Fighters (in other words, WIN). My only concern is WHAT could have done this, fearing ALIENS DUN IT and hoping for ALTERNATE HISTORY

both Russia and China have the resources and manpower (if not the brass tacks [for now]) to initiate something like that.
Russia couldn't even make Georgia, a small former Soviet satellite RIGHT NEXT TO IT look like that, let alone D.C. In it's grand Soviet days, maybe, but now it's only friends are small nations with idiots for leaders asking "TANK PLZ."
As far as China's concerned, they have enough trouble keeping lawyers scared, civilians in line, and mouths fed to endure the political and economic fallout of a war with the US, let alone put up any sort of fight. China as it stands is as delicate a house of cards as a tragic portion of their buildings.
In summery, no, I don't believe Russia or China pose a realistic threat now or in the near future, especially when each continues to fall further and further behind technologically.
Now another option as seen in the trailer is random terrorist being the perpetrators, perhaps covertly moving into the D.C. area under the guise of civilians and utilizing synchronized bombings all over the city before launching a full assault, but this brings to mind two questions; How will the immigrant community respond to such a depiction and would terrorist really want to attack an entire city as crime ridden as D.C.? it's like a scorched earth policy in the Sahara.
