Just use Google Docs then. Yes, it’s Google. Yes, it will somewhat tie you into their ecosystem but Google Docs are free, get regular updates and are pretty good overall. I’ve been using Google Docs for many years now. I occasionally use Office365 for work and Google Docs is just as good, if not better.
It could be true, I guess. It could be Western propaganda too. It doesn’t take much to reason a country as underdeveloped and isolated as NK lacks an effective military.
However, maybe they don’t need to be particularly good to further Russia’s interests. NK army may be good enough as cannon fodder or purely for defence purposes, as border guards or patrols.
