In regard to foreign wars that have gone on for almost 20 years, he wants all troops home from Afghanistan, Iraq, Syria and probably most NATO countries. But he's getting push back from the General's and Pentagon and advisors like John Bolton (read Neo Cons) who pushed to hard to keep the status quo. These guys never met a war they didn't like.
In regard to healthcare, like most repeal and replace Republican's they don't have a complete program. Allowing insurance companies the ability to write policies outside of states, and allowing small employers to gather together as groups across industries and state lines would be a start but they can't even get that done. However, Trump is pushing hard to lower drug prices.
While he's used the term hoax. I believe, he would likely acknowledge climate change but also knows that it will be costly to the American economy. I believe the climate is changing as it has for millennium. But how much is our responsibility? I live in Florida. Can't dig a hole without hitting seashells. That's because at one time Florida was essentially a coral reef totally under water. Did humans cause that? So if sea levels rise 2 inches over the next 100 years it may mean the earth is returning to norm.
Energy is a successful Trump initiative for America. We had the Iranians attack the world's largest refinery in Saudi Arabia, shoot down our drone, take oil tankers and the US killed Salami. Oil markets rose a modest $10 - $15 per barrel. Years ago it would be over $100 per barrel. That's why Bush and Obama never messed with Iran. They didn't want gasoline in the US back over $4 per gallon. Now with our new energy independence we can tell them to fuck off. And business in America thrives since energy prices are stable and low.
In regard to elections. How many Russians voted in Michigan, PA and Wisc? None. How many of those votes were influenced by Russia. None. If your going to bitch at anybody that hurt HRC try Comey who is now a Democrat hero. But he may have cost her thousands of votes.
That is all.
China is truly the only threat and that's because they continue to steal our technology. Trump is trying to stop that.
