Is Gerhard Schoeder of Germany ignorant, troll or stupid?

Ukraine is going to conduct a counter-attack against Russians in the southern part of the country. The fightback is extremely important as it has been well prepared, and troops are numerous and equipped with modern western weaponry. 

Therefore I consider the following days to become some of the most important ones during the war. If Ukrainians fail, it provides a lot of confidence to Vladimir Putin´s military force. But if Ukrainians will succeed, that will turn the situation also in Donbas and Luhansk, where Russians have thus far had some success. 

Therefore is was extremely unwise from Gerhard Schoeder of Germany to insist diplomacy as the only way to end the war. In my opinion, a man with such a long history in politics should understand that the only outcome from diplomacy would be acceptance of Russian violence. And that is not acceptable. 

It should also be noted that General Pekka Toveri noted Russians to have - theoretically - a huge reserve of soldiers, but it seems to be difficult to mobilize them into the front. Therefore, spending time with diplomacy would work only for Russians, and against Ukrainian attempts to keep their independence.

Therefore we should ask, whether Schröder is Putin´s troll, ignorant about facts or simply stupid?
