Not irrelevant at all. It is a minor point and a parsing of words for an obvious insult.
Sorry, not buying what you’re selling.
I’m not “selling” anything. I’m not disputing your analysis Obama’s antipathy toward Israel, and Netanyahu personally. I’ve not attempted to be insulting. I’m simply pointing out that there is an important difference between a Head (or Chief) of State, and a Head of Government. There are also important differences in protocol between an official State Visit, and a working visit by a HoG. Perhaps, you can’t grasp these distinctions because your President is both HoG and HoS. Whenever Obama travels, he’s given the HoS treatment, because that’s one of his roles.
BTW, I was wrong to say, in my first post above, that the USA is the only major nation with a combined HoS/HoG — Brazil is another (I did say “AFAIK”). That would have been a full-blown State visit, complete with the only State dinner at the White House, planned for this year. Formal State visits are a rare event everywhere.
