How the Revolutionaries Will Declare War Against the Celestial Dragons

So this arc, we know that the revolutionary army will declare war against the celestial dragons. But how will they do this?

I believe they will do two things.
1. Free the celestial dragon slaves
2. "Kidnap" vegapunk

The first seems pretty obvious to me. The slaves of mariejois are the most oppressed people in all of the world. It just seems characteristic of monkey d dragon to wish to save these people. In addition we know from hancock's backstory that the slaves are sometimes fed devil fruits for fun. This means that if dragon saves them, he could gain a powerful army of devil fruit users at his disposal.

As for vegapunk. We know that the world government arrested vegapunk for his science. This along with the fact that kuma is working for dragon makes it very likely that vegapunk might have a secret alliance with dragon. If this is true, then I think dragon might save vegapunk from the world government this arc.

This is because in caesar clown's flashback, he stated that if akainu was fleet admiral, he would approve of caesar's cruel science experiments. This is foreshadowing that caesar will replace vegapunk in the future.

Anyways leave your thoughts in the comments below. How do you think the revolutinary will declare war.
