I see nobody is interested in my question on why there is lack of corresponding scrutiny into the development problems experienced by anyone other than the US. A subject which should be of equal enthusiasm.
I don't think I actually have a lack of interest in that topic, the (embarrasing?) truth is that I actually haven't really thought about it in the past and as such wasn't ready to answer right away. And probably am still not really now.
Since I only really understand german and english, and a lot of those details aren't translated out of the respective countries' languages, I can't really comment on anything outside GER, the US and UK I guess.
In Germany there is an equivallent to the "Government Accountability Office". They give out criticism on programs, but most of the time it's about how a program is handled / managed, I feel they don't really do in detail technical analysis and critique.
Then there are agencies within the DoD that manage programs and do technical evaluation of concepts, progress, end products. But there is, for all I know, no specific agency tasked with playing "the devil's advocate" on defence programs. If that is what you describe the DOTE to be.
From my point, and that is totally subjective, it appears that these discussions are indeed "louder" in the US than in other places. Maybe because of political culture or perhaps there's just a lot more money involved in the US then anywhere else.
Finally, the topic of defence, in Germany, is much less visible in the public domain then in many other countries I believe. Most people have a general idea of if they want military commitment in certain places or some kind of capabilities available to the armed forces.
But when in comes to technical details, even politicians / officials concered with the topic may not really be in the know; perhaps simply because there's not much to gain in GER by being technicly adept in defence topics ...
I don't know if that really helps you or if it is what you are looking for. I honestly cannot do better right now as I really haven't thought about this properly.
