A "not so smart" bomb made out of an inflatable boat, 2 suicidal maniacs
and a lot of explosives almost taking out the Cole - thats assymetric
warfare.

The term "Asymetric warfare" does not neccesarily indicate a low technology
approach aganist a mighty opponent,it might also contain the highest end
approach.
For example,Imperial Germanys decision to counter surface might of RN with
submarines is a classical example of "Asymetric warfare" even though submarines
were not the products of lower technology than surface ships.

So in future, advanced nations might try to take out everything their opponents
have by using weapons based on emerging technologies,while less capable nations
or organizations might try to achieve something by digging soil near fiberoptic
junctions.
Both could be called "Asymetric warfare" by definition.
