Former President Barack Obama took several thinly veiled shots at President Donald Trump and "strongman politics" during a speech in Johannesburg this week.

Without mentioning Trump by name, Obama said that we "are living in strange and uncertain times."

He told the crowd that he is "not being alarmist [but] simply stating the facts."

"Strongman politics are ascendant suddenly. Whereby, elections and some pretenses of democracy are maintained [but] those in power seek to undermine every institution or norm that gives democracy meaning," Obama said at the event, which marked what would be the 100th birthday of Nelson Mandela.

Obama said that international progress is "threatened by the rise of nationalism," but told the crowd that the world has been through "darker times."

Obama also quoted Mandela in one of his apparent jabs, saying that people are not born racist or discriminatory, but "people must learn to hate."

"They can be taught to love," he added, quoting the late anti-apartheid leader.
