Seriously, dude? Did you at all click on the links in the OP?
The issues, as I see it, and as I indicated in my title, is that Trump speaks "not a lick" of a foreign language. Our past three POTUSes have had some measure of mastery of a second language. And truly, were this the 1980s, I wouldn't mention it. But it's not the '80s. It's the 21st century. People routinely make friends and acquaintanceships with folks in other countries. Even Trump does. People travel to and do business in other countries. Trump most certainly has. Hell, the man's had two wives from Eastern Europe and he's buddies with Russians. One'd think he'd have picked up some sort of basic conversation skill in at least one of the two (if not three) Slavic languages to which he had to have had routine enough exposure and an able helper -- either of two of his wives -- to learn it. And yet he's not even got a partial mastery of either.
Hell, I wouldn't call myself fluent in any language other than English, but I can hold an intermediate level conversation in French, Spanish and a very basic one in Mandarin, and I can't read or write Mandarin. Remember, in my title, I wrote "not a lick." I wrote that because (1) I know that Trump's educational background, exposure to foreign language speakers and mine are similar enough that it's not unreasonable that he'd have, had he made any effort at all, acquired a "partial mastery" of some language other than English, and (2) I'm not expecting of him more than I accomplished "by osmosis" and formal education. I'm well aware of how much and how little effort I put into picking up each language I can speak to any degree, and because I do, I know it doesn't take much to pick up a language; it mostly takes just trying to do it.
