Trump tried many times to work deals in Russia. No law against it. We have this thing called the World Economy. It's cool. Countries trade with each other for mutual benefit. Despite many attempts and many visits over the years, Trump never closed a major deal. No law against that, either. Not even when he was a Democrat, did he close a major business deal in Russia. Not only is that failure, legal, it's also remarkable. This is all silly. But I'll answer the question of the Devil's Advocate: if it turned out that some business tie between Russia and Trump Enterprises were irrefutably established-- say, via a subsidiary acquired after such a deal or a subsidiary divested-- the only reasonable and rational answer would be "So what." Again, there this thing called the World Economy. And there's another thing called International Trade. They're legal and they're cool. And they sure beat war. Again: this is all silly.
