Wars, elections, terrorism have always existed, and if by "elections" you mean Trump, business in general would not care (of course, some businesses may benefit more from this or that candidate). Business has been and is being done regardless of politics for ages. The guy who organized the already heavily ailing GDR (East Germany) another 5 billion DM credit in 1983 was the most right-wing party head of Germany at the time - the political differences between the players can hardly be any more extreme. Terrorism has in Europe has been much higher in previous decades - Germany, Spain, Britain (and I may forget a few other countries) all had their own very active domestic terrorists.

What's the use of pointing to negative interest rates - if you can't make money with the business you'd always lose even more. Same reason why pointing to tax rates is disingenuous except for special cases - either a business makes sense or it doesn't. If you don't show a profit tax levels there's no need to worry about tax levels. Same goes for your example, if the business does not seem viable what use is it to point to an overall difficult situation, should you continue investing into what you think is a bad business just because of that?
