When have the Jedi/Republic have had a Lasting Victory?
The RO2 doesn't count, they purposely hid.
And after the Emperor was destroyed, much of the GE was still there but no leader. Until Thrawn Came Along.
And the GE is arguably the 2nd most succesful Empire ever. They destoryed the Republic which has never been done before and destroyed ALL of the JEDI. Who cares how long it lasted, they achieved the almighty goal.
I wouldn`t say `all`.
