Hi ! I honestly recommend Cambridge University (UK) and in France, I second ShowroomDummy and highly praise the EHESS - graduated from there in Social Anthropology (MA) but the IR program is really strong as well + the way the department works is really nice, you can take seminars from any discipline and PhDs are really short in France (3 years) which can be an asset if you don't want to study forever
SciencePo has a great reputation, but honestly, from an academic POV, doesn't live up to its reputation. You might consider it however for the various possibilities of foreign exchanges if that's something you're looking for ! SciencePo will be more strict on residency, and the EHESS way more flexible, also things to consider. The INALCO is amazing if what really matters for you is a strong regional focus, and maybe a very peculiar set of local languages or local politics.
