If Lithuania had not imposed this blockade when it did, it is not clear the European Union would have forced it to do so. In this sense the blockade was a strategic decision on the part of Lithuania. One view of Lithuania’s strategy is that it is forcing or inducing its allies to affirm their support, at a more rather than less favorable moment in the hostilities.

A nested game is what it sounds like -- a game within a game. It recognizes that the actors in most real-world settings are not unified and have conflicting motives. The classic example is the failure of a proposed Middle East peace deal because some hard-line faction sponsored a terror attack or an assassination. The agreement was never just the two sides dealing with each other; each side was also dealing with its own internal conflicts.
