Like always actions speak louder than words. However look at our own history starting with the Spanish civil war. What did Britain do then officially. Volunteers yes official forces no. War between countries is not fought ad lib . It has always had to by convention have an official Declaration . Those who have in our lifetime have broken that rule have ultimately been defeated and at the moment that is the way it is going to happen again. The morality of Spain, Germany , Italy, Japan, all broke the morality rules and Russia has now broken them as well , regardless of their reasons they are in the wrong and one way or another the Russian people will inadvertently pay for it. The total Ruling party of Russia is wrong for letting it happen. The rules were broken and that is it. But as said when this started there are other countries who in a larger conflict would side with Russia , and that will be Russia’s only Hope at this moment in time . If things appear to be going in that direction stand by for the biggest bang in history. JS
PS Hitler took advantage of that civil war to use and exercise his Luftwaffe for the coming offensives which he intended to carry out, which couldn’t be more blatant , and any doubt of his intentions should have stuck out like a sore thumb. JS
