Not lovers, not fighters !

Could Jedi have won that clone war, anyway ?
We know from TPM that they "can't fight a war", and from AOTC that they're "keepers of the peace, not soldiers".

And it's true, the Jedi code encourages negociation over agression, understanding over arrogance.
Such peace-loving and pacific attitude, along with a strong concern for individuals (Jedi tend to consider their role as unique and kind of elite) could throw the Jedi at large into a bottomless pit of doubt and dilemma, when an all-out war rages outside the temple doors.
Who to save, who to sacrifice ? If (as we're told several times) the Jedi stood their pacifist ground for a millenia, they might simply not be able to act as a war faction, not willing to lose a single unit (be it clone), or even worse, a fellow Jedi...

I feel those three years of war since AOTC did more spiritual than physical damage to the Jedi, hardening them after the unavoidable casualties, distorting their very approach of the Force.
Manipulated and overhelmed, the "old school" Jedi can't win this war. And my feeling is that this is just a part of you-know-who's master plan.

As for the love part, that feeling is seen I think as selfless and pure by the Jedi.
Sadly, that very feeling that is supposed to guide them is going to destroy them.
Love struck the "chosen one", at the worst possible time, placing Anakin in a position where his options narrow to just one: the Dark Helmet way :)
And again, I am pretty convinced the whole chain of events that put him where he is in ROTS is not due to chance at all.
