Tartare, ISTR that the RAF bombers didn't use chaff for a while in WW2 because we were worried it would be copied and used against us at a time when we couldn't counter it.
In the modern world I doubt the tech in this is beyond what other countries could produce, they just haven't, if they got one it would still take plenty of time and effort to prototype and productionise it, and a huge amount of time testing it to make it work for them.
I guess it is a balancing act of effectiveness of existing counter measures v's emerging threats, I doubt a doppler zero cloud of chaff works against any modern threat system.
