One thing I notice about state-level espionage and backdoors. The USA seems to have an affinity for hardware interdiction as opposed to software backdoors. Hardware backdoors make sense since much of it passes through the USA.
Other countries such as Israel are playing the long-con with very well engineered, multi-year software backdoors. A much harder game to play.
