I sometimes believe the reason why SunTzu is required reading for today's maneuver warfare student, is a veiled communication to warn the military officer about the fog of war.
When applied to domestic enemies against the constitution, who have already won many a victory within our government and not been held accoutable for their traitorous activities, the fog of war is directly applicable.
When one studies the long range goals and consistent operational art of communism and socialism, I also wonder if Communist China doesn't have very real intentions of overtaking the US and our sovereignty, but has not yet acted to an outright military invasion, simply because they can gain so much more by not appearing to pose an outward military threat.
This then leads me to consider how much the US has lessened in military power from 20 years ago and again from 60 years ago, along with the newer maneuver warfare as applied in our victory in Iraq. I don't see much preventing the Chinese from a similar styled military campaign through most of the US should they devote themselves to it.
In evaluating these ideas, I also observe Clinton's later year correspondance with Mexico, China and Vietnam along with his attempts in the Balkans to appease the Muslims.
When meglamaiacs stop receiving power, they frequently have no qualms in resorting to any form of criminal behavior imaginable. I wouldn't be surprised if the same socialists in our government, wouldn't sell out the US, even to acting as fifth columnists in an invasion by foreign enemies, if they believed they would become powerful representatives of that foreign power in their victory.
If the socialists don't retake the White House in the next 8 years, I suspect the risk of foriegn threats directly upon our homeland will increase from their direct involvement. If they do land in the White House, I suspect they will further emasculate our ability to defend the Constitution.
IMHO, the sooner they are removed from power and brought to justice the less chance of direct threats to the COnstitution.
