The legitimacy of a war is not established by how it is organized but by what it achieves.

For the Democrats, they're trying to avoid having the Sanders-Clinton debate over and over again. But, to some degree, they're sentenced to that debate. Clinton is much more embracing of the global economy and the international world order. Sanders and Warren are much less so. And they have got to figure out which side the party is on, if they're going to have a clear message. I think this is probably one you probably can't straddle.
