The post consists of a headline and a link stating that a mapping service has relabeled Lake Ontario as “Lake America” on U.S. phones. The President offers no words of his own, which leaves the reader to guess whether this is a report, a boast, or a request.
Omitted is any acknowledgment that the lake borders another country, which presumably continues to call it what it has long been called. A label changed on a phone is not the same as a body of water changing.
