As 2016 comes to a close, world leaders appear just as eager to start fresh in the new year.

President-elect Donald Trump, however, couldn’t let this year go without taking another dig at his critics.

“Happy New Year to all, including to my many enemies and those who have fought me and lost so badly they just don’t know what to do. Love!” he tweeted Saturday morning.

Trump’s 2016 was capped by his presidential win in November, but he has feuded repeatedly with Democrats, members of his own Republican Party, celebrities and the media.

His praise of Russian President Vladimir Putin on Friday continued to rankle his detractors, who support sanctions against Russia for allegedly interfering in the U.S. election.

Putin in his New Year’s address, which began airing Saturday in distant parts of Russia, wished happiness for his people — and recognized 2016 was a complicated year for the nation. Russia has been tied to the hacking scandal against the U.S., and remains deeply involved in the Syrian civil war.

“It wasn’t easy, but the hardships that we have faced have brought us together, have motivated us to open huge reserves of our potential to move forward,” Putin said. “The main thing is that we believe in ourselves, in our strength, in our country.”

President Barack Obama used his final New Year’s message to America to look back at his administration’s accomplishments for the past eight years, touting Obamacare, the killing of Osama bin Laden and restoring ties with Cuba as gains.
