Sounds like much ado about nothing to me. Prior to this did you even know you had an Ambassador to Estonia? *laughs*
Lol, you are seriously asking me if I knew if the US had an ambassador in Estonia? The US has has an ambassador at the overwhelming majority of nations, save for the ones that actively anti-American in sentiment.
Yes, I was aware that the US sent ambassadors to places including Estonia... That being said, I keep up with geopolitics, while most don't, so I'm sure there are plenty of Americans who don't.
*Ado about nothing*. I'm not sure entirely what this refers to. I mean, if slowly losing allies etc. isn't a concern to you, then yea, I mean, why would anyone care? I mean, if you are Estonian, and you prefer to remain a free country, it might be somewhat concerning to you that the US president appears to be attacking NATO, the one organization that actually guarantees Baltic states the chance of remaining independent countries indefinitely, , you might fight yourself vaguely concerned that a past ambassador, who was friendly to Estonia and actually understands what their national concerns were and brought them up the USGov, which apparently worked for Estonians, you know, like decades...
Me, personally, I think one of the better benefits of Trump is his ability to more or less slowly destroy the majority of the US's past gains regarding its diplomacy, which just means other countries are less likely to help the US whenever it inevitable finds itself fighting another war on aggression. The slow degradation of the US's power over various regions of the world is not a bad thing if you impose the US's imperial actions.
