U.S. President Donald Trump (R-FL) said the decision to expel Russia from the G8 enabled the war in Ukraine [1, 2].

This assertion challenges the diplomatic consensus of several Western allies by suggesting that isolating the Kremlin accelerated the path toward armed conflict. By linking the current war to a specific policy decision from years prior, Trump is framing the conflict as a failure of diplomatic architecture rather than solely an act of aggression.

Trump made the comments during the G7 summit in Kananaskis, Alberta, Canada, in June 2024 [2]. He said former U.S. President Barack Obama (D-IL) and former Canadian Prime Minister Justin Trudeau were responsible for the decision to remove Russia from the group [1, 2].

According to Trump, maintaining Russia's membership in the G8 would have preserved the necessary diplomatic channels to prevent the escalation of tensions [1, 2]. He said that the exclusion of the Russian leader removed a critical layer of international oversight and communication.

"If Putin were in the G8, this wouldn’t have happened," Trump said [1].

The president said that the shift from the G8 to the G7 created a vacuum in high-level diplomacy that contributed to the eventual invasion of Ukraine [1, 2].

"You wouldn’t have had the war," Trump said [2].

Trump's remarks come as the G7 continues to coordinate sanctions and military aid to support Ukraine. His perspective suggests a preference for inclusive diplomacy with Russia, even during periods of high tension, over the strategy of isolation pursued by the Obama administration and its allies [1, 2].

"If Putin were in the G8, this wouldn’t have happened."

This claim highlights a fundamental disagreement between Trump and the established foreign policy of the G7 regarding 'deterrence through isolation.' While the G7 has operated on the premise that Russia's exclusion was a necessary response to aggression, Trump's argument posits that such isolation removes the 'off-ramps' required to prevent full-scale war. This suggests a potential shift in future U.S. diplomatic engagement with the Kremlin.
