Relations between Benjamin Netanyahu and Barack Obama were documented as strained throughout the period they held office simultaneously. Ten years later, with Israeli voters set to go to the polls in a narrowly contested race, the two have renewed their public dispute.

Speaking at an event in Belfast — footage of which circulated online — Obama told attendees he had raised these points directly with Netanyahu during his time in office. Obama argued that the party holding greater power bears a particular responsibility to act on that advantage rather than use it as licence to take unilateral action and forgo accommodation with others, adding that while such an approach might yield results in the near term, it would ultimately prove harmful to Israel itself. Netanyahu responded to those remarks on Friday by taking issue with them publicly without referring to Obama by name.

Obama's remarks also extended to Hamas, the group responsible for the 7 October 2023 assault on Israel, which Obama addressed with pointed disapproval.

Obama's comments on the founding of Israel in 1948 against the backdrop of the Holocaust drew considerable attention in Israeli media coverage. The speech included a passage in which Obama described Jewish people as having faced persecution, discrimination, and killing across centuries. He placed responsibility for a substantial portion of that population movement on Europe, noting that those who relocated had defensible grounds for doing so, pulled toward areas where their communities had maintained ties rooted in history. He added that while the first point stood on solid ground, the dispossession of those people's land was, in his view, equally impossible to dispute.

Obama described the Palestinians as having been expelled, adding that their desire to reclaim the land was an understandable response to what they viewed as an injustice. Netanyahu subsequently posted a video featuring those remarks and characterised them as regrettable, countering that the Jewish people hold ancestral ties to the land and are not foreign occupiers within it.

A spokesperson put forward the position that available historical documentation leaves the mechanisms of colonial administration largely unaccounted for. Netanyahu described the territory as the ancestral home of his people, not land taken from others. "Judea is what it's called," he said, referring to the ancient scriptural name applied to the southern portion of the West Bank, a territory that came under Israeli control following the 1967 war.

Netanyahu, who holds the record as Israel's longest-serving prime minister, has maintained strong ties to the Republican administration under Donald Trump, and the two leaders have built a close working relationship. Relations between Netanyahu and Obama grew strained throughout the 2009–2017 period, with Netanyahu at times coordinating with Republican figures to voice opposition to the administration's diplomatic approach toward Iran.

With a close vote approaching on 27 October, Netanyahu has made repeated appeals to his electorate, claiming that outside forces are working against him. That message has included pointed criticism directed at New York Mayor Zohran Mamdani, who has been vocal in his opposition to Israel.
