If you did want to edit this sentence, you could change the phrasing so you don’t use “leaders” twice, and perhaps cut out the vague and overused phrase “making a stand” — i.e., “We can strengthen our leadership skills by examining the greatest acts of our historical leaders,” or something like that.

Being great leaders requires that we make a stand and we stay strong like the great historical leaders in our history.

We can be great by making a stand and being strong like some of our historical leaders.

Using our great historical leaders to guide our way we can make a stand and be great ourselves.

The old guys in the past are cool and did cool stuff; we can do cool stuff too.
