You could replace caused for solved and have it mean as much.

Try to recall that Slavery as a concept was largely ended world wide by the BRITISH NAVY, not Lincoln.  Our little bar brawl was only a bit of the story.

Most dictatorships end with coups, palace intrigue, or natural death, rarely with wars.

And many foreign invasions succeed.  Depends what side you are on as to whether its a foreign invasion or a righting of an old wrong.

Cute, but no truism.
