“There’s nothing more sacred than our democracy, but Donald Trump’s ready to burn it all down,” a narrator said in the ad, which is airing in battleground states.

Biden, 81, was thousands of miles away from Washington when Trump showed up, participating in the G7 summit in Italy. It’s the second foreign trip in two weeks he is using an as allegory for a US presidential season he is trying to cast as a fight to save American democracy. Unveiling a series of new plans to boost Ukraine diplomatically, militarily and economically, the president recalled that the US and its allies had been repeatedly asked whether they’d stand firm for a country that Russian President Vladimir Putin was trying to wipe off the map.

“We will say it again, yes, again and again and again we’re going to stand with Ukraine,” Biden said, as he stood with Ukrainian President Volodymyr Zelensky. A flurry of initiatives to institutionalize Western support for Ukraine being unveiled at the summit are a clear effort to hedge against the possibility that Trump could return to power on January 20, 2025. The ex-president frequently cozied up to Putin while in office and has said he’d end the war in Ukraine in 24 hours — a feat that could only be achieved by locking in Russia’s territorial gains after its brutal invasion

Former Trump national security adviser John Bolton warned on Thursday that Biden could not guarantee that the 10-year pact that covers military training, intelligence cooperation and other areas that he signed with Zelensky on Thursday would last.

“I think it is illusory, though, for anyone to think Trump would be bound by it. If Trump is inaugurated at noon on January 20 next year, by about five after noon he could have dissolved this agreement in its entirety,” Bolton told Bianna Golodryga on CNN International.

If Trump gets elected and does walk away from Ukraine, he will complete the transformation of a Republican Party that once prided itself in standing up for democracy worldwide and that, under President Ronald Reagan, won the Cold War.

“You can’t bind a future president who doesn’t want to be bound,” Bolton said.
