What they are actually arrogant about remains unclear.

If the solution is to pull out of the war, it kind of hits a snag if Palpatine has the ingenious idea of saying no, and sends the very betrayed feeling Clones to conscript them. The Separatists also can continue to attack whenever they want.

Anakin is also a problem. Even if the Jedi somehow successfully pull out, he will want to continue fighting, feel betrayed and end up closer to Palpatine if they don't back him up.
