"Why would they just leave?"

What business did they have on Dressrosa other than making the situation clear? Why would they have stayed? And no, making his subordinates bring over the news would cause disbelief anyways. It's better that government officials came to solve the issue. Stick around after they were done? What? I thought they left soon after. They were most likely leaving when Robin and co saw them.
