KIEV, Ukraine (AP) — Ukrainian President Petro Poroshenko shook up his faltering military Thursday, appointing a new defense minister and top general while speaking angrily about the years of decay and corruption that left the forces unable to deal effectively with the well-armed eastern insurgency.

His tougher tone, analysts say, reflects public pressure to continue the fight against the insurgents in the regions bordering Russia— even with a rickety military that’s had little success.
