How about internet mis-information??? Get the IED makers in the construction phase.

There are great internet talents in phishing and such. Use the same strategies to discredit valid IED instructions and give false instructions that either destroy the fabricators (like suggesting using ammonia and chlorine - which will form a noxious gas immediately that will knock out those present) or that implant a detectable element that the troops will be alert to.

How do we get these ideas to the appropriate thinkers/doers?

Then the US would be accused of censorship and tampering with public information - which the Liberals and Democrats would promptly slam them for.

The more I think about it the more I believe the insurgents are being funded by MoveOn.org.
