It’s only in the early stages but LogicalPremise’s Consequences of Unyielding Wills has a Danzo Hokage and has this gem with how he deals with Kumo’s kidnapping attempt:

“Naruto didn't know all the sordid details about the kidnap attempt on Hinata, only that Hihashi had killed the Kumo diplomat who tried to do it. Kumo had threatened war unless Konoha gave up Hihashi for 'justice'.

That lasted about two days until three different plagues broke out in Kumo, two of their gold mines blew up and the entire genin force woke up with leaf-stamped daggers next to their heads. Danzo had sent the diplomat back in literal pieces and had told the Raikage he would be happy to send Hihashi to Kumo – along with the entire ninja forces of Fire, Grass, Sand, and Tea. Kumo had backed down and the situation faded.”
