Trump not qualified to be president – Obama

Outgoing President Barack Obama condemned Donald Trump as unsuitable to be commander-in-chief Thursday, after the Republican nominee blasted US military brass and praised Vladimir Putin.

“I don’t think the guy’s qualified to be president of the United States and every time he speaks, that opinion is confirmed,” Obama said in unusually caustic language while overseas.

Obama is in Laos for a summit with South East Asia leaders and his final trip to east Asia.

“I can tell you from the interactions I have had over the last eight or nine days with foreign leaders that this is serious business,” Obama said.

“You actually have to know what you are talking about and you actually have to have done your homework. When you speak, it should actually reflect thought out policy you can implement.”

Trump on Wednesday raised eyebrows by saying that Russia’s president was “far more” of a leader than Obama.

Putin is “very much of a leader,” Trump said in a televised interview.

“It’s a very different system, and I don’t happen to like the system. But certainly in that system he’s been a leader, far more than our president has been a leader.”

Trump also drew fire for criticising the military.

“The generals have been reduced to rubble,” Trump said, before noting he had “faith in certain of the commanders”.

The bombastic mogul will face Hillary Clinton in November’s election, which the Democratic former first lady is tipped to win.

Trump has previously angered many in the military community with mocking remarks against US Senator and former prisoner of war John McCain for being captured in Vietnam.

Obama is expected to hit the campaign trail with Clinton when he returns to the United States, with voter turnout likely to be a key theme.

Obama won the 2008 and 2012 presidential elections handily by mustering large numbers of young, black, Latino and Asian voters to go to the polls.
