The R's always accept growth in government, and move on. The same with being fiscally conservative...they talk the talk, but they don't walk the walk. That is too bad, but that is the status quo that I hoped Trump would be able to change. I think he's made progress on regulations, but definitely not on spending.
Regarding his trade policy...it is interesting that you say "at what cost." You look at an opening gambit of a negotiation as if it is the final goal, and you cry, "At what cost!?" If the opening gambit were the goal, then I might be as worried as you are, but I don't think it is, so I'm not. I could be wrong of course. But, if he want's X, he needs to demand 3X and negotiate downward, even if people like you will scream "3X?!!! That's outrageous!!" and then "He only got X when he tried for 3X. What a failure!"
My Russia comment was an attempt at humor, since I know you too well. Trump has fought the Russians in Syria, and provided arms to Ukraine, sanctioned Russia, put troops in Poland, bolstered air defense of the Baltic states, and his tough love operates to make a stronger and more independent NATO which is definitely against Russia's interest. He could definitely do more (although he has already been more anti-Russia than Obama), but it is a balancing act.
