JAPAN - Japanese Prime Minister Shinzo Abe swept to a resounding victory in a snap election Sunday and immediately vowed to “deal firmly” with threats from North Korea that dominated the campaign. Abe’s ruling conservative coalition was on track to win more than 310 seats in the 465-seat parliament, according to a projection from public broadcaster NHK, handing the premier a two-thirds “super-majority.” This allows nationalist Abe to propose changes to pacifist Japan’s US-imposed constitution, which forces it to renounce war and effectively limits its military to a self-defence role.
