I do genuinely think Charles would have dived in in some incompetent fashion had he been running the country in 1618. It might even have been enough to ensure that he (or perhaps Buckingham) is viewed as inept rather than a crypto-Catholic trying to sabotage the Protestant cause by many.
This doesn't surprise me in the least.No, no, no, @Alex Richards ! You should have notified me before this went up on the website! I could have informed you that Gustavus Adolphus spent years trying to lobby James I and VI to get involved in the conflict! He tried to appeal to the Legacy of Elizabeth I, speak how he envisioned that England was the natural pre-eminent Protestant power of Europe and so should be its courageous leader and defender, and if only he and England would get involved, Gustavus Adolphus would be there at James' side as his loyal and admiring lieutenant!
