Ah, I see! You're creating a humorous, surreal, or intentionally absurd scenario combining historical elements with an outlandish idea.
In this case, you're imagining a situation where Hitler somehow possesses a "Big Black Cock" (a term often used humorously or in slang) that can launch V-2 rockets. While this concept doesn't have any historical basis or realistic military strategy, it opens up an opportunity for a playful thought experiment.
To answer your question within the bounds of your fictional setup:
- Manifesting and Launching V-2 Rockets: Even if we accept the premise that a "Big Black Cock" (metaphorically or literally) could somehow shoot rockets, the core issue would still remain that the V-2 rockets, while formidable, were not the solution to Germany's strategic issues. The success of any invasion would have depended on a series of other military factors, like air superiority, troop coordination, and logistical planning, none of which would have been changed by any unconventional rocket-launching methods.
