Yes... And Pigs are able to fly!
So you assume every countries are stupid and only Germany is ready and mobilized during 1938?
-First... If crisis happen people start to mobilize and Germany is not mobilized during 1938, it is not prepared to invade nothing and it need to pick upd equipment , move troops and arm them in some time, so it is not ready..
-Second.. Italy was a dictatorship, no parliament needed to mobilize troops and a war was fought some year before so... French have troops ready and need the same time as Germany to mobilize. You know that Parliament need time , but military staff act on the order of the government so if it say to the army to start to be prepared unofficially or officially it can become to get ready before officially stuff needed. With state of emergency and decrees also those stuff can be faster into Parliament. The same for others countries.
-The 3 million men is explained due reserve that are in every army. If reserve were mobilized numbers grown. However looking the source, i don't know if trust it.
-The italian army was bad equipped for colonial/desert war out of their mainland but it was fully capable to defend mainland cause it don't have to be splitted and know the terrain. Without count Alpini were one of the best troops fighting on the mountains.
The problem is you assume Hitler is a genius and every others are dumb. The germans troops were able just to annex those lands, they were not ready to fight an entire army, but with a league opposing with arms they won't have just occupied everything so fast.Each move would have be done thinking about a possible reaction.
Yes, the only problem would be that Austria border to Italy is all mountain. Germans have to invade Yugoslavia to attack throught Carso and they would need nearly all their army concentrated there leaving all the French line uncovered..
You don't seems to know that there are mountain over all over the north of italy, there is no way to pass without cross them and there are a lot of fortified positions that don't make stuffs you say so easy.Ah there are also mines camps that can be done between those narrow passes, and how would perform a panzer division over Carso? Do you think that Italians that have already beaten austrians and germans after they lost at Caporetto would leave their country to Germans so easly? Do you have a clue how many opposed to germans occupations? And the population was split between fascist and socialist... Think about all togheter against germans
Without count Britain help and, French help if the germans break the line throught the Alps.
I like to see you take German page as source cause that make me clear why you say this.
I can come up with other sources about the state of the italian army. You deny the simple truth, thats all.
I never wrote what you try to insinuate.
And your sentence, why a german chooses a german site as a source, shows exactly your intention and the direction where you come from.

Whence will you know what we germans think of the italians? Did you live in germany?
I lived three years in Italy, my wife is a italian. So please accuse someone else.
Hitler was no genius, he was a moron as your famed Il duce was a moron. No guy with enough brain, had started the second world war, or as the Duce, had jumped on the train of doom.
And please show me the mountains in the Po valley, from Venetia straight through to Turin there is no mountain. There are some hills thats it.
The mountains are south of the line of Piacenza to Bologna. Or north from the line Milano to Verona.
Sure not all Divisions where poorly lead the Alpini and some armored Divisions fought bravely, but thats it. You can´t win a war with WW I equipment and doctrine in 1938 or 1940.
Here is another source:
"Italian Cowardice in World War II: Myth Versus Reality
The performance of the Italian armed forces during the
Second World War has been the butt of jokes for over 70 years. However, the notion that the Italian military fought poorly and surrendered readily is not exactly true as there are examples of Italian forces fighting quite successfully and bravely.
But the widespread belief seemed to be that the Italians were cowards, with disasters such as the failed takeover of a much weaker Greece and ineffective fighting in North Africa used as evidence. While these and other military mistakes by Italy do stand out, these debacles
were not due to soldiers' cowardice: what the Italian military lacked during their offensive campaigns was not bravery, but modern weaponry and good leadership, along with a clear lack of desire to achieve Mussolini's goals.
Poor Weaponry
When Germany invaded Poland in 1939, Italy was in no way ready for an offensive war. However,
Mussolini desperately wanted to participate in the redrawing of the map of Europe and overlooked the state of Italy's military-industrial complex in order to feed his ego. Italian industrial power was a mere fraction of that of Britain, France or Germany and was not ready to produce the guns, ammunition, artillery, tanks, and trucks on the scale that was needed. When Italy entered the War in 1940, its forces were equipped
more in line with the First World War, rather than the Second."
Of all the major military forces involved at the start of World War II,
Italy had the by far the least competent high command. Mussolini filled the officer positions with men whose only "qualification" was loyalty to Il Duce. Before the start of hostilities, Italy did have some capable generals - especially those who experienced the mistakes made during the First World War. However, things would change once Mussolini attempted to militarize Italy as he would purge the country of anyone whose allegiance was questioned. Many men from titled families, whose ancestors had been fighting for centuries were considered more loyal to the King, and so stripped of their status and given menial positions."
In retrospect, it almost seems that the Italian military was doomed to failure from the start and was thrown into a war that they were not equipped for, nor willing to fight for Mussolini's cronies. The very fact that Italy became an aggressor during the war was solely
to appease the arrogance of Mussolini, without a thought to the preparation of the country. The military lacked leadership and modern weapons, yet it was still thrust into battle. When ill-equipped forces of disheartened men were defeated, Il Duce could not see his own mistakes and simply labeled his men as cowards. However, it has been shown that while under command of competent German leadership, Italian troops fought very well - contributing to the final defeat of Greece and
acts of great bravery on the Russian front.
In conclusion, it was these factors and not cowardice that lead to Italy's poor performance during World War II."

Thats from a italian internet site. I can easily pull other sites out of my had.
For your crisis, germany walks into austria, the other states have to respond to this move, so germany is on the initiative, not Italy or France. Or do you think germany would sound a big trumpet and says hello world in three months we invade Austria? Please mobilize first?
Why should germany need her whole army? Poland Campaign 63 Divisions, Yugoslavia was done with 26 Divisions, Greece 12 Divisions. The Metaxas Line was broken, in the Mountains, guess how many Divisions Germany needed? One Mountain Division and a Battallion of Stug III two days later the Line was broken.
If we assume Italy had all their 1940 Divisions ready in 1938 (73 Army Divs and 9 Border Guards), so we have to assume that germany and france had all their 1940 Divisions ready, thats only fair. So we have 134 german Divisions against 84 French Divisions, 14 Fortress Divisions, 73 Italian Divs plus the 9 Border Guard Divisions.
France didn´t wanted to go on the offensiv, their whole plan evolved around the maginot line, germany had around 20 Divs on the French border in 1939. Lets say germany put another 20 Divisions on the Italian border, what will Italy do? Go on the offensive? I think, they would sit on their butt like their french buddies.
So germany has the initiative and around 90 Divisions ready to strike where and when they want. Thats game over for the Czechs and Poland. By the way, why would the Czechs and Poland risk a war over Austria?
And why should the UK enter the war, because France or Italy wanted another war? Hardly, i think the UK will tell France or Italy, sorry no interest boys.
The whole assumption germany would invade and annex Austria against the oposition of Italy, France, UK, Poland and Czechia is a no brainer, even Hitler was not dumb enough to try it.
