Hi Kitkat22! Congratulations on your multiple offers. I went to SAIS and did MA. I think you should give SAIS a serious consideration because of your interests, network, and location.
With SAIS MIPP, you can choose to be affiliated with any concentration (whether issues or regions). Based on your interests, it seems like strategic studies (as we call it "strat") would be your best match. Apart from rigorous classes, SAIS offers many interesting activities and on-campus events that feature speakers who work in the public and private sectors. I feel that I learnt a lot from classes and from events that I attended. Plus there are so many interesting talks at think tanks around the area. And of course opportunities to build your network. I also know that MIPP program has their own brown bag lunch/happy hours. SAIS has been hiring new professors too. That means there are cool classes that you can take. My friend is taking a course on cybersecurity taught by a new professor.
The only drawback for me is the rent in DC.
