alas, since the crack downs, turkey just does not care about international opinion (they have a cordial relationship with russia, and donald seems to admire Erdoğan). they will probably just shell it for a while.
I actually think they care a lot about international opinion, but not always in the most healthy way. Turkey seems to be primarily interested in playing spoiler, keeping an eye on economic interests, and exercising their refugee destination card in a beneficial manner. They've got an interesting balancing act going between their increasingly strong Russian alliance and their membership in the European community.
