The good news: your troops come back with combat experience, the first North Koreans to have it since the 1950s

The bad news: your troops come back hooked on internet porn.

You can set up veterans-only porn dispensaries on the national intranet to mitigate that (the state’s hackers can steal it in between emptying Bitcoin wallets for the nuclear programme, or you can set up a domestic porn industry for the military), though what if they are also have become used to freer access to information and speech in general?

The other option, of course, is to make sure nobody comes back alive; like Icelandic racehorses, once your troops leave your pure country, they may never return, lest they contaminate it.
