Nobunaga says: "Nightingale, if you do not sing, I shall kill you."
Hideyoshi says: "Nightingale, if you do not sing, I shall make you."
Ieyasu says: "Nightingale, if you do not sing now, I shall wait until you do."
Honestly (though I like Ieyasu and Oda both) I think Ieyasu's answer is the most wise...
You raise a lot of good points though, thanks.
And yes the Hiei incident was very Ruthless (why I made mention of it in my initial post), but was anything Tokugawa did any less? I mean he's the one who killed all the Christians and foriengers.
Anyway... this has been bothering me for some time but I never really liked any of the anti-nobunaga series and stuff (well Onimusha a bit) until now.
Ieyasu was not wise, he was an opportunist and he was lucky. The timing couldn't be more perfect for him because Nobunaga and Hideyoshi did all the work for him. If Nobunaga was not betrayed, Ieyasu would probably be waiting forever.
