President Obama is making no guarantees to President-elect Trump that he’ll remain a passive and respectful ex-president.

At a press conference Sunday night in Lima, Peru, Obama was asked whether he’ll “withhold public criticism for President Trump” in much the same way President George W. Bush withheld publicly criticizing him during his two terms in the White House. He couldn’t give his successor the same guarantee his predecessor gave him.

“I want to be respectful of the office and give the president-elect an opportunity to put forward his platform and his arguments without somebody popping off in every instance,” Obama told the press in Lima, the last leg of his final foreign trip as president.

But he warned Trump: “As an American citizen who cares deeply about our country, if there are issues that have less to do with the specifics of some legislative proposal or battle, but go to core questions about our values and our ideals, and if I think that it’s necessary or helpful for me to defend those ideals, then I’ll examine it when it comes.”

How Obama plans to “defend those ideals” he didn’t say. For now, the current president is looking forward to getting off the job, at which point he’ll “take Michelle on vacation, get some rest, spend time with my girls, and do some writing, do some thinking.”

“I have to take Michelle on vacation,” he added.

Obama was also asked whether his party’s electoral defeat signals the end of the Democratic Party.

“Well, no, I’m not worried about being the last Democratic president. I think — not even for a while. And I say that, not being cute,” Obama said, citing Hillary Clinton winning the popular vote.

He also blamed “political bad luck,” “structural problems” and the Democratic strategy of “micro-targeting” for Clinton’s defeat to Trump in the presidential election earlier this month.
