The main weakness of the Italian army was the poor quality of personnel, and not just the officers. The rank and file gave up too easily.
Good leaders can make up for poor equipment and are vital for the morale of the troops. Just look at the PLA (Chinese Civil War or Korea), heavily outgunned both times, but were able to achive their basic objectives regardless.
The Turks would've had to give in to German demands to allow the passage of troops given obvious German superiority and the vulnerability of Istanbul
All the more reason why they would have called their friends the Soviets in to help out.
The Reich had already shown it meant business in Yugoslavia and elsewhere.
Well actually the Reich invaded Yugoslavia in part because it underwent a revolution. What lesson was Turkey supposed to draw from that apart for 'don't change horses in mid-stream'?
Historically Russia and Turkey were enemies.
I'm getting pretty sick of giving you history lessons, especially since it seems to have no effect on your shield of 'self assurance' (I could use a more choice term here, but I'll try to remain civil). But, one last try.
Eastern Turkey was not entirely under the control of the new Turkish government during the revolution, particularly the parts that had Armenian majorities. Soviet troops stepped in and assisted Turkish troops. So, the modern Turkish state was founded on joint effort between the powers.
When building the USSR, specific exceptions were made,
in order to make the Turks happy. It had originally been planned to mash all the Caucasian republics together as one unit, but keeping Muslim and Turkic populations seperate was seen as a necessary item for relations with Turkey.
When Socialism in One Country was drawn up by Stalin, he in part had Kemalist Turkey in mind. He drew favourable comparisons with Turkey's development and political model on numerous occasions (just sift through some of his speechs for around 1926-1927). So, mutual respect.
Finally, there are no examples of Stalin trying his luck with Turkey before WWII. He was quite happy to test his Northern, Eastern and Western borders (as well as playing around in Xinjiang, which is now in China...). Yet he doesn't attack Turkey.
Any paralell you can draw with Imperial Russia would be a waste of time, the Soviet Union was not a true successor state.
Iran was occupied only after the Reich attacked Russia.
Since your playing with alternative timelines, what is to say the Soviets don't accelerate their moves in Iran? It would be in Britain's interests to do it to boot, so why not earlier?
Russia would not have gone to war against Germany unless its own territory was invaded.
Mmm... So when Stalin offered to fight the Germans in Czechoslovakia on behalf of the allies in 1938 he was just protecting his own territory? The only reason the plan fell through was there was no one to support him and the Poles vetoed the movement of Soviet troops.
Of course the Russians were aware of great German tactical and strategic proficiency; the campaigns of 1939-40 had proven that beyond a doubt.
So Soviet military people saw it with their own eyes did they? And the General Staff were competant enough to absorb this lesson? The Soviets would have just dumped all their received wisdom from the Civil War (eg. the best way to stop an offensive is a counter-attack)? The Soviets would have completely believed the press coming out of Britain and Germany?
Surely you've heard of Stumbling Colossus?
Yes, its a text by Glantz... could you be more specific?
Given all the problems the Russians faced, I doubt they were in a position to implement anything but defensive plans
They had been consistantly on the offensive in the late 1930s and early 40s, what makes you think this would change?
The Russians had taken some steps to improve their security by annexing territory but that doesn't mean they planned to initiate war.
What it isn't a sign of is that Stalin was afraid of the German war machine or taking a purely defensive posture. You claimed both these things and they were simply wrong.
The Reich could've taken the near east and a setback of that magnitude could have led to the ouster of Churchill, and peace, before the US entered the war.
My emphasis on could. After Churchill took over the peace elements had been pushed to the outer reaches of political debate, the odds of them coming back were very poor.
The Vichy French would've been crushed and occupied if they went too far.
How do German forces intend to reach Algeria? You have just diverted their strength to the Balkans and possibly Egypt, so no land invasion for you, and their sea lift capacity was terrible (see Operation Sealion or lack there of). Even France itself would be a bit of a stretch with your strategy. France wouldn't even be a convenient resting place for troops at that point.
Any substantial increase in U-boat strength prior to '42 would've been a disaster for the US, had it entered the war.
Since you have failed to suggest how they would expand production enough to achive this, I counter with an equally pointless statement.
If Churchill had UFO technology, Hitler would have been ray-gunned in 1940.
