I'm aware that the President likes to go on television and beg me to call him to ask for troops. I find it strange, as Chicago doesn't want troops. I also have experience asking him for assistance – just to have the rug pulled up from underneath me when execution meets reality.

For example, in some states (although not IL to my knowledge) getting energy assistance funds might require screening by an ICE database. In energy world, in many places this is the only aid available. I will have a fuller analysis out by the end of this year to share.

Someone asked me what victory against the forces seeking to occupy Chicago looks like. Obviously, those forces being repelled is the goal, but there are layers to what success looks like in these deteriorating conditions. The first is to successfully resist the normalization of military occupation.
