All the issues that have made us so week that even the communist Chinese and seventh century savages can take advantage of us. That is what we have done to ourselves. That is what we need to fix ourselves.
Trump is silent on this.
I think you have to watch the Hannity interview, Part I. He addressed our putting ourselves into debt to the Chinese, and how he would change that; he also addressed our creating OPEC, funding the potentates of the Middle East through buying their oil, and that we should keep Iraqi oil as a spoil of war to at least pay back the $1.5T we spent to free them of Heussein. Not MY idea of silent.
