we've learned with barack obama is what you don't do can be every bit as consequential as what you do do. in some ways he's overreaction to george bush kae into office saying i'm not going into iraq, not have large forces in the middle east, not going to make that mistake again. so what he did was make his own set of mistakes. goes into libya, doesn't follow up. misses any number of opportunities to do useful things in syria, pulls u.s. forces out of iraq, puts a calendar on u.s. forces in afghanistan. signs a questionable agreement with iran. doesn't react in certain ways to the russian invasion of ukraine. so i think history will basically say that he missed a lot of opportunities to deal with the challenges of this day. >> 100 years from now, historians are going to look at america at the turn of the century and see a country that's just unrivaled in power. at any time since roman empire.
