For North Korean leader Kim Jong-Un that meant overseeing a long-range artillery drill, simulating a strike on the offices and official residence of his South Korean counterpart, Park Geun-Hye.
Park, meanwhile, countered by accusing Kim of leading his country down an ultimately destructive path and stressing the need for a drastic change of direction by the regime in Pyongyang.
Tensions between the two Koreas have been rising since North Korea carried out its fourth nuclear test in January, and a satellite rocket launch a month later that was widely seen as a disguised ballistic missile test.
Pyongyang has upped the rhetorical ante in recent weeks, with near daily threats of nuclear and conventional strikes against the South and the US mainland in response to large-scale South-US war games.
On Wednesday, it warned of a "miserable end" facing Park Geun-Hye, with its artillery units standing ready to turn the presidential Blue House in Seoul into a "sea of flames and ashes".
According to a report by the North's official KCNA news agency on Friday, Kim took that warning a step further by ordering and personally monitoring a live-fire exercise involving the same target.
"Artillery shells flew like lightning and intensely and fiercely struck targets simulating Cheong Wa Dae and rebel governing bodies in Seoul," the North's official KCNA news agency said.
Cheong Wa Dae is the Korean name for the Blue House.
According to KCNA, it was the largest drill of its type ever conducted, involving "hundreds of different types" of long-range artillery.
"If the enemies challenge us... our artillery forces' merciless retaliating blow will turn Seoul into rubble and ashes," Kim was quoted as saying.
The North's ruling party newspaper, Rodong Sinmun, published around 40 colour photos of the drill in its Friday edition, showing Kim watching through binoculars as multiple batteries of heavy-caliber artillery units and missile rocket launchers pounded an offshore island from a beach.
South Korea's Yonhap news agency cited military sources as saying the exercise was held Thursday near the eastern port city of Wonsan.
The North always reacts strongly to the annual South-US military exercises, which it sees as provocative rehearsals for invasion.
