host: let's hear from kelley vlahos.ow there is a debate about industrial policy and whether or not too much of our pipelines, and this is an overall debate we are happening, too much of the pipelines and defense pipelines are actually in hock with the chinese and they could turn off spigots at any time. and a piece of any weapons system could be completely curtailed if they decided to be rep beautiful on that score. there is a conversation about supply lines, monopolies. i don't know if nationalizing it is the way to go. i am sure you would get much opposition there. but i do feel this is a conversation, as much of our industry has gone overseas and the most protective of them being the military. if we are flying planes with components made in china where they could literally shut off radar or other very important key technologies, that is a concern and i know there plenty of people writing about it. host: kelley vlahos with her perspective. thank you for being with us. still to come, we focus on global covid-19 vaccina
