Donald Trump has suggested terrorist attacks in France and Germany were their "own fault" and citizens of those "compromised" countries could be subject to "extreme vetting" before entering the US.

Trump was elaborating on a policy he announced in his Republican convention speech on Thursday.When asked in an interview with NBC News if that might lead to a point when not a lot of people from overseas are allowed in, the Republican presidential nominee said: "Maybe we get to that point."He said France and Germany had "totally" been compromised by terrorism. Trump said:"You know why? It's their own fault because they allowed people to come into their territory."We have to have tough, we're going to have, tough standards. If a person can't prove what they have to be able to prove they're not coming into this country."He added: "That's why Brexit happened okay? Because the UK is saying, 'We're tired of this stuff, what's going on? We're tired of it'."Here's my plan, here is what I want - extreme vetting."Michael Moore, the Oscar-winning documentary-maker known for films such as Bowling For Columbine and Fahrenheit 9/11, has caused consternation among his admirers by telling audiences that he believes Trump will beat Hillary Clinton in the race to become US president.Appearing on the discussion show Real Time, with Bill Maher on Wednesday, Moore elicited boos from the studio audience when he told the panel: "I'm sorry to be the buzzkill here so early on, but I think Trump is gonna win."On election morning the angry, white, male voters - white men over 35 are only 19% of the country but that's 40 million voters - and I'm telling you, they are going to be out there, rabid, excited [to vote]."Addressing a press conference earlier, he said: "[Trump] knows how to manipulate a dumbed-down population . He's not as stupid as he looks."..
