providing intelligence and low gistic support. do you think it s going to stay in that limited role? i think it certainly will. this is a very tenuous internal conflict. there s a lot of people attempting to make it into a much bigger proxy war of tehran against riyadh, the saudis against the iranians, the shia against the sunnis. but this war has been going on many years inside of yemen. i think the u.s. provide support of saudi arabia in the context of logistic support that secretary kerry has already promised. there could be troops on the ground if saudi arabia crosses that border what we see is a continuing convoy. it s focused on the houthis. but another group is there too. is this going to ignore one group and focus on the houthis?
