In local context, Valais, Neuchâtel, and Geneva[4].
Less recently, the scots-irish in northern ireland, cyprus, korea, israel, not to mention Lawrence of Arabia or the former ottoman balkans in general[5].
The mongols are said to have offered neighbouring cities the thirteenth century equivalent of "plata o plomo", although in their case the silver would flow the other direction...
In ancient context, the opening lines of the Melian dialogue occur with the Athenian delegation saying "everyone in this room knows why you all force us to address the aristocracy instead of the people — you all know the people would be unable to refuse our offer."
Too many to bother looking up in between and before, so I won't multiply examples.
[1] The US no longer needs B-52's for aerial minelaying. I don't know how much mining might affect Brest, but it would certainly be a bummer for Rotterdam and Genoa. I trust brit HN'ers won't wind up eating chlorinated chicken but I guess we have to wait for Oceanian domestic politics to resolve before that question will be answered. In any event, the UK mantle of "inside the tent, pissing in" seems to have already been passed to poland and hungary.
[2] which came over wholesale, not retail, so maybe it shouldn't count. If it does, maybe we can add the original 13 colonies, as what would become canada frankly declined to join them.
Contrary to popular opinion, I believe "Екатерина, ты была не права" would be anachronistic if referring to Alaska, and refers instead to Catherine's sudden refusal to send George any troops to help put down the bitter dead-ender terrorists (and, later, foreign fighters) who famously had had an arms cache in Concord.
[3] with current interest in southeast asian sea routes, I bet the USN would like to have Subic Bay back. Unfortunately at the moment it's been redeveloped in luxury condos and yachts (being within bugout distance of Hong Kong), so it might be rather more expensive than when it was ceded.
[4] "Liberated" by the french with a fair amount of domestic popular support. Attached to us by everyone not the french, because while all of the great powers wanted our territory, the only stable strategy in 1815 was for them to agree that none of them would get it.
[5] Having studied their latin and greek, the english, while they had their empire, made good use of "let's you and him fight."
