Ukrainian President Volodymyr Zelensky, who has been successful in procuring over $100 billion from the United States under Biden's leadership, posted to X: "Ukraine is grateful to President Biden for his unwavering support for Ukraine's fight for freedom, which, along with strong bipartisan support in the United States, has been and continues to be critical. Many strong decisions have been made in recent years and they will be remembered as bold steps taken by President Biden in response to challenging times. And we respect today's tough but strong decision. We will always be thankful for President Biden's leadership. He supported our country during the most dramatic moment in history, assisted us in preventing Putin from occupying our country, and has continued to support us throughout this terrible war. The current situation in Ukraine and all of Europe is no less challenging, and we sincerely hope that America's continued strong leadership will prevent Russian evil from succeeding or making its aggression pay off."
Both Zelensky and Israel's Prime Minister Benjamin Netanyahu have been embroiled in ongoing wars with Russia and Hamas, respectively, and have relied heavily on American aid, something that Biden has been more than willing to provide. As Netanyahu departed for a trip to the US Monday morning, he stated to reporters that he will "seek to anchor the bipartisan support that is so important for Israel, and I will tell my friends on both sides of the aisle that regardless of whoever the American people choose as their president, Israel remains America's indispensable and strong ally in the middle east" even as "there is great political uncertainty in Washington."
"As I departed for the United States, I thanked President Biden for the many things he did for the State of Israel during the war and his years as President, Vice President, and Senator. I look forward to my important meeting with the President," Netanyahu posted with his remarks.
Over in the UK, newly elected left-wing Prime Minister Keir Starmer posted: "I respect President Biden's decision and I look forward to us working together during the remainder of his presidency. I know that, as he has done throughout his remarkable career, he will have made his decision based on what he believes is best for the American people."
His counterpart in Poland, Donald Tusk, said, "You’ve taken many difficult decisions thanks to which Poland, America and the world are safer, and democracy stronger. I know you were driven by the same motivations when announcing your final decision. Probably the most difficult one in your life."
In the US's neighbor, Canada, Prime Minister Justin Trudeau posted: "I’ve known President Biden for years. He’s a great man, and everything he does is guided by his love for his country. As President, he is a partner to Canadians — and a true friend. To President Biden and the First Lady: thank you."
In Russia, however, the Kremlin's response to Biden's exit was not as gracious or enthused. "There are still 4 months to go before the election,” Kremlin spokesman Dmitry Peskov told Russian media Life.ru, per NBC News. "This is a long period of time, during which a lot can change. We need to pay attention, monitor what will happen next and mind our own business."
