"Do you see the issue with prioritizing the ends too much over the means?"
What ends do you mean here?
"For me, the issue isn’t just that he’s a businessman with a one-track mind in achieving his goals (economic or otherwise). But he’s one that lacks tact as well. If you disrespect a business or partner that you hold more leverage over than they hold on you, then that approach helps you become dominant."
Okay, well, if he treats his presidency with the same kind of business manners he has to build his empire, then whatever the amount of "tact" he uses is more than enough.
"In politics though, your businesses and partners take affronts personally, whether they should or not. Trump probably could strongarm in a lot of matters, because his “business” is the United States now. It doesn’t get much bigger. But say the wrong thing to the wrong country (maybe even a close ally of the wrong country,) and it could cost us all."
Cost us all what? With who? You do realize that no matter what relationship you define the US under with any nation, WE are the dominant ones? I mean this is a pretty big assumption, and I'd like some clear examples of who you feel it can co st us with?
"…do you think Trump, compared to other potential leaders, is likely to say something to offend another group of people?"
Depending on which group of people. You do realize that no leader in the US had universal love an admiration – right? I'm not particularly threatened, or worried about a President that offends people. That to me is insignificant to how that President's policies affect the economic, and thus domestic well being.
I stand by that a businessman or a mogul, is a hell of a lot better equipped and prepared to handle that than a community organizer, a lawyer, or a politician that makes 200,000 for a speech.
In the election, I voted for Johnson, who also has a lot of business know hows, and has translated that to a generally good governorship.
"I’d think so. Heck, some people voted for him, because they liked that about him.
Should that happen, it won’t get Likes on Twitter. It might just piss off people who are already unhappy with the US."
Like who? Europe? China? Russia?
"I don’t think our leverage in the course of the next 4 years will be so great that Trump can strongarm for whatever we need without taking the needs and wants of other countries into account."
Our leverage in global affairs to the biggest hit in the longest time under President Obama.
Undermining our Allies in the Mid-East and giving a massive financial boost to a major Middle East player, Iran, who happens to also be a major destabalizing force in the mid-East told our other allies around the globe that you know what, if it comes to US interests, we are more than happy to put you under the bus.
Or drawing a line in the sand for Syria to cross, and then doing absolutely nothing when they did sent clear message to the world that we simply are not going to protect you.
Not making a bigger stance in Ukraine which we SWORE to do in the early 90s?
But hell! He can get a Nobel Peace Prize, eh?
"That’s why I’m concerned with his personality about prioritizing the bottom line too much and being callous to those ends. That’s business. It might not work in politics."
Whether it works in politics or not, is irrelevant. If he set's a business friendly agenda; i.e lower taxes, better trade policies, less regulation, or encourage business lending, he only needs the already Republican majority to set out the legislation.
Politics matters the most when he's running for office (he isn't. He won.) and when he needs to negotiate with the other side to pass his agenda (and he has both house and senate on his side).
At this point, his demeanor towards whoever isn't nearly as relevent as to what he actually accomplishes.
At best, we would have a major economic boom.
At worst, nothing much will change.
