Whatever happened in Marine Ford wouldnt have affected World Peace, and it will only harm the Pirates or Marines, so Dragon stayed out.
And it isnt that just cuz Sabu had his two "brothers" their, doesnt mean Dragon will listen to him, he is got a whole world to set free.
If one of two "brothers" was his son than it does matter
If one of two "brothers" was his son than it does matter
He trusted that he would endure and survive, or since he already left him at birth, he probably doesnt give a ****.
The only one Dragon might risk everything for is Luffy, he won't let the revolutionary army be at risk for someone like Ace, he might not even do it for Luffy though I would like to believe that he would do it for Luffy
i mean, the war was broadcasted over the whole world and dragon knew luffy was there and he clearly said "luffy is a grown man", he didn't do anything...
the war didn't last for days, even if he wanted he probably couldn't have come there in time
It was announced in the papers though, I forget how long for.
It wasn't announced that Luffy was gonna be there
