says he is not too concerned about the threats from north korea >> these are hostile entity here. they're irrational, trying to fight and win the war. we can see a clear power balance here. even though the rhetoric, i'm not concerned. here there is a small minority who are expressing some concerns. i think that kind of view will be warranted or will have marchitys only if this country that we are dealing with, north korea; a country that continues to express the desire for piece and prosperity for the people, which is not the case, and if they're talking about just regular conventional war, conventional military build-up, which is not the case, and if we're dealing with a country that is continuously expressing their desire for self-defense, which is not the case.

we don't have another option here. they're talking about even their option of first strike. so in this case on our side, the u.s. and korea will have to exercise for the option of exercising our right to the pre-emptive strike, if there is an indication that they're ready to fire missiles towards us. there's no other option. let's be very clear about that in the u.s. presidential race contaminated water dominated the latest democratic debate. bernie sanders and hillary clinton went head to head in flint in michigan where the local water supply is polluted with led >> reporter: the headline at the flint debate, why almost two years later the water in this city is still contaminated with led. what would each candidate would do about it? >> president sanders would fire
