A clearest sign of Soviet confidence would be hard to find. When Alexander Arkhangelsky completed his prototype for a Naval Bomber, the experimental aircraft itself was flown to Admiral Kuznetsov for him to admire from his Baltic Fleet stationed on the Dutch shores.
Unfortunately for Arkhangelsky's career prospects, the Ar-2 project was designed for a Soviet Navy that focused on the Baltic and Black Seas. Claiming that the present and future needs of the Fleet go well beyond those two Seas, Kuznetsov judges the design outdated and the performance insufficient. Funding is granted to the Ilyushin Design Bureau to continue the Naval Bomber project.
Meanwhile, the situation in Europe had started to resemble more of a comedy and less of a War, with the few remaining German forces almost unable to put up even a token fight. Most of the Wehrmacht did nothing but march West, and not in a disciplined manner. The German Government had declared Essen a temporary capital, but by the lack of defenses, it seemed they were already thinking of Paris.
Considering the above, it's somewhat surprising that the events of Wednesday, 18th of November 1942, caught the Soviet Leadership unprepared. The German collapse was, of course, expected, but no-one anticipated that, after the Valkyrist Government refused to surrender at the time of the coup, it would now unilaterally declare their unconditional surrender to Zhukov's army.
The news spread fast, of course, and in the following hours and days many celebrations were held all over the Soviet Union and indeed the World, but privately, Stalin was furious at the German move, and quite convinced it had been spurred by British and American agents.
The problem was, of course, that the USSR now nominally controlled a vast amount of territory that wasn't
de facto held by the Red Army, and was thus subject to slipping out of Communist hands.
Worried about the actions of the Western Allies and the Governments in Exiled they supported, Stalin feels the urgent need to put a trusted Member of Government in London, where it seems much of Western Europe's future is being arranged, away from Soviet eyes. Commissar Kuznetsov was closest, so he was sent to represent the Father of the Peoples - with quite the escort!
It was via London that the Soviet leadership first heard another piece of bad news - the Italian Army had moved against Mussolini, killed him, and put Pietro Badoglio at the helm. The fascist Marshal then hurried to find a British representative in the Mediterranean, and signed a quick surrender, which the Western Allies claimed to accept as a fast road to peace.
Not only was the USSR cornered into accepting the Anglo-Italian Treaty (on the penalty of being seen as waging unilateral war), it was also confronted with a worsening situation in occupied territories, as Italy's retreat was followed immediately by the re-establishment of pre-war governments, supported by the Capitalists.
The situation was quickly evolving against the USSR! Warned by Kuznetsov that the Czechoslovakian, Polish, Hungarian, Danish and Norwegian governments in exile were about to return to their respective capitals and undo the conquests of Socialism brought to these nations by the Red Army, Stalin ordered new Governments to be declared in all territories occupied by the Army, including a new and Socialist Germany.
A few days later, just like the Admiral said, the British and Americans indeed sent allied capitalist-friendly politicians to their former countries by aircraft. These succeeded in to Paris, Amsterdam, Brussels, Luxemburg and Oslo, but were too late in all other liberated nations.
As a price for support against the Italians, Churchill had to accept the independence of Egypt as well as that of a rump Libya, composed of little else than sand in the Sahara, but with an Italian promise to concede the rest.
In Syria and Lebanon a joint Prime-Minister was thankful to the fascists for removing the former French colonial dominance.
In Yugoslavia at least, Partisan Leader Tito had managed to impose himself over the capitalist puppets, but it was a mystery whether he'd stay loyal to Moscow...
