The whole "The Jedi Order fundamentally failed" thing. Obi Wan and Yoda proceeded to exile themselves, I don't think they were really in the mood to fight back. And just kind of doing the thing that failed again really wasn't a good idea - Luke doing this was why the new republic collapsed again between Eps 6 and 7.

Also, even if they were top tier Jedi, two Jedi and some toddlers wouldn't be able to compete with The Empire - who would be much more aggressively hunting them if it was known they were actively training new anti-Empire warriors.
