I actually mostly agree and was being a bit sarcastic. Training on newer systems is prohibitive anyway as you mentioned. Sending personell is clearly provocative and should be avoided. I just find the argument that the military industrial complex ran out of the bullets to help is laughable.
Obviously, production increases with demand and lags it causing stockpiles to decrease until output increases. Hopefully the quoted assessment is talking about that dip and not a more serious problem.
Really though, Russia knows the US is obligated to help. They signed the memorandum too, after all. It’s hard to argue with someone that does so in bad faith, but continuing aid is hardly a provocative act.
That’s just how research works most of the time. The experimental setup required to build a working prototype and prove the initial hypothesis is always going to be larger and more complex than a mass market appliance. If that appliance ever gets built depends on a huge number of factors too. If the process scales as expected, how complex the device is to produce and if a company thinks that it can make money on it. The researchers, meanwhile, are probably more worried about their next grant funding.
