It seems that way, probably, because the wait time right now is 11.5 months for an interview.

This is exactly correct. It's not about geopolitical timing, it's always been about convincing the specific consular officer interviewing the person wanting to travel that they will return home. My suggestion is to travel with him elsewhere. Over time, a history of international travel will be a note in his favor. Never a guarantee, but it could help.
