ambassador to the u.n. and fox news contributor. good to have you here, ambassador. >> glad to be with you. martha: that puts them in a tough spot, doesn't it? >> i think the administration is correct to move additional assets particularly roosevelt into that area. it is critical for international commerce going from the strait into the red sea on the suez canal and obviously coming out the other way and there is concern about iran's continued support for the houthi coalition. this is not new. this has been going on for years. martha: right. >> in particular in the battle for aden the critical seaport there, the houthi and their yemeni allies have been being pushed back. so the prospect of iran trying to intervene to help them hold on to significant parts of aden really is, i think a major issue and tactical sense in the battle for yemen. martha: got it. i think everybody sees the strategic reason why we want to have very strong presence there right now.
