Now Donald Trump says he could abandon Japan because they can 'sit at home and watch Sony television' if the US is attacked

  • Trump told Iowa crowd Friday that Japan isn't committed to defending US
  • He also complained about other allies not paying their dues to NATO 
  • Germany, South Korea and Saudi Arabia also sparked his anger 
  • The presidential hopeful said he's prepared to 'walk' if they don't deal 

Donald Trump announced Friday that he would 'walk' from Japan and other US allies if they don't commit to defending America and pay their 'fair share' of NATO fees. 

'You know we have a treaty with Japan, where if Japan is attacked, we have to use the full force and might of the United States,' Trump said to a crowd in Iowa.

'If we're attacked, Japan doesn't have to do anything. They can sit home and watch Sony television, OK?'

Walking away: Donald Trump announced Friday that he is prepared to 'walk' from US allies who don't pay their 'fare share' towards NATO or agree to defend America 

Walking away: Donald Trump announced Friday that he is prepared to 'walk' from US allies who don't pay their 'fare share' towards NATO or agree to defend America 

The slam came during a speech in which Trump complained about countries under US protection, such as Japan and South Korea, and others that he said do not make large enough financial contributions to NATO. 

The presidential hopeful said that the United States protects Japan, South Korea, Germany, Saudi Arabia and other nations, but 'they don't pay anything near what it costs.'

'They have to pay. Because this isn't 40 years ago,' he added. 'It's got to be a two-way street.'

Japan's alliance with Washington has been the bedrock of its defense since the end of World War II, and the country still hosts 47,000 US troops.  

'You always have to be prepared to walk,' Trump said about getting allies to carry their financial weight on Friday.

'I don't think we'll walk, I don't think it's going to be necessary. It could be, though.'

His remarks on Friday revived complaints he made in April that NATO member states should begin paying their 'fair share.'

He also said in the April speech that Japan and South Korea must be prepared to arm themselves to deter a threat from North Korea.
