I think we can trust the Russians to put any NATO-nationals under extreme duress to disclose their allegiance and purpose in being captured as (potential) non-combatants.

Most definitely. Those reporting that are in Ukraine have stated this is a war against Russia and NATO. There is a reason why Finland and Sweden are rushing their NATO memberships thru. These countries border Russia and NATO wants an excuse to bring their military to Russia. Same as Ukraine. They invaded the Donbas areas (Russians and mainly speaking Russians) after they trashed the Minsk Accord in 2014. AZOV was formed that same year. AZOV and the Ukraine Military have killed 24,000 Donbas civilians since 2014. Remember, this area was annexed by the agreement to leave these Russians alone. Many had been born there. But the ink was just dry on the Accord and AZOV moved in. That steelworks had $billions poured into it via the US taxpayers. Zelinsky had visits from Noname, Lindsay Graham, back then who pledged money. And today the worst of the worst NAZIS, like Pelosi, Schiff, Boris Johnson, and many world NAZI leaders have come to kiss the feet of globalist puppet Zelinsky. Why? NATO desperately wanted this war. But it has backfired badly. Russia has cut gas and electricity off to European countries in the last few days. Namely Poland, Finland and others as they too refuse to pay in Rubles or Gold. The EU CANNOT survive with Russian energy. The word out is Putin is playing it cool and allowed a grace for payment but that is up. There is talk that come September ALL Russian energy will be disconnected to Europe, except to Hungary and Serbia. Putin has had enough. India and China will replace Europe in gas supplies and Europe will collapse. Europe and NATO have pushed the bear once to often and the Bear has roared back.
