BlairWitch749, I'm starting to assume that this is a waste of my time but...
1) This insistence that something be declared possible because you want it to be declared so or based on entirely separate and distinct historical events is becoming tiresome. The Soviet fleet was vastly weaker than the British nor was the Soviet air force very effective, nor was Sevastapol comparable to Gibralter.
The British will not send supply ships past before they had supressed German artillery and a single British battleship would be able to massacre most of that German artillery outside the range of the Germans to shoot back so there had better be a major Luftwaffe presence to prevent that. If the British conclude that a night action while a fleet escorting a large number of merchant vessels blows past might be worth the risk to a battleship, with fighter coverage out of the Canaries then even that might not be enough.
2) How about dicking over several nations seen by Germany as desirable allies, turning one nation seen as a desirable ally into an active enemy and outraging Germany's major ally of Italy?
3) In other words you see nothing wrong with effectively dissolving the occupation of France.

Instead you again try to hijack the thread to your fantasy of a communist Spain. You might also want to check out the actual rate of German military expansion before making claims about Germany's 'leisurely' rate of war production.
4) Most of the units and especially the officers and NCOs did have such experience and the British don't need to send 34 divisions to Spain, they need to provide Spain with sufficient support, primarily in the air and in terms of equipment, to prevent a rapid overrun by Germany. Given Spain's own large number of troops, mostly combat veterans, and an even larger number of men who were serving in combat only recently, plus the extremely rugged terrain only recently fought over, this is quite possible. Also the 34 divisions were only part of what the British had for the war effort.
5) For the last time the topic is NOT an ASB scenario of a Stalinist Spain being invaded by Hitler. If you can not offer a response except to try to hijack the thread then you are wasting my time.
6) In other words you believe that the diversion of a good portion of the Luftwaffe's strength to Spain along with a massive logistical burden will
not weaken Germany elsewhere.
7) I see you intend to continue your delusion that the USSR's much smaller fleet and merchant marine was comparable to the British fleet and merchant marine and that the British will confidentally send merchant ships into German range without taking any action about the German artillery first.
8) More claims, in particular those about supposed Spanish forces preferring Hitler over Franco, plus abandoning Sea Lion much earlier than OTL, and no evidence to justify either claim. Plus an assumption that the divisions and aircraft parked in Spain won't be missed or that Hitler will suddenly conclude a desperate need to make up for the Spanish occupation as he did not from the forces occupying so many other nations.
