The reaction over Charlie Kirk's assassination touched yet another constituency this week: the collection of world leaders gathered at the United Nations.

Two weeks after Kirk was shot and killed in Utah, several of the world leaders including those from Serbia, Paraguay and Ukraine, referenced the conservative activist's slaying — and some of the divisive outpouring of reaction to it — as evidence of deeper fissures in global society as the U.N. General Assembly is held this week.

Decrying the “sick expression of joy for the crime committed against an innocent person,” Serbian President Alexsandar Vucic told assembled leaders on Wednesday that reaction to Kirk’s death represents “the best confirmation of that.”

Kirk was assassinated during a Sept. 10 event at Utah Valley University. U.S. President Donald Trump and other administration leaders gathered Sunday at a memorial service, where other speakers noted the worldwide reaction to Kirk’s death, mentioning areas around the world where memorials had sprung up.

Paraguayan President Santiago Peña also mentioned Kirk in his speech Wednesday, saying in Spanish that he was “shaken, saddened, and distressed” by Kirk's killing and arguing that the “macabre response must awaken us from our sleepy state of complacency.”

Earlier in the day, Ukrainian President Volodomyr Zelenskyy mentioned Kirk, as well as last month's stabbing death of Ukrainian refugee Iryna Zarutska on Charlotte’s light rail system, as representative of “headlines about violent attacks happening all around the world.”

Kirk was a provocateur who at times engaged in language that was racist, misogynistic, anti-immigrant and transphobic.

That has drawn backlash from conservatives who view the criticism as cherry-picking a few select moments to insult the legacy of an inspirational conservative leader.
