Exercise 2: Which Montevideo Criterion Is in Doubt for an Unrecognized Breakaway Region — Possible Solution
=================================================================================================================

The chapter's own real Montevideo Convention criteria are: a permanent
population, a defined territory, a functioning government, and the
capacity to enter into relations with other states. The scenario
explicitly confirms the region already has the first three - a real
permanent population, a defined and defended territory, and a
functioning government - so those three criteria are genuinely
satisfied.

The one criterion left in real doubt is the fourth: capacity to enter
into relations with other states. The scenario states directly that no
other country will actually establish diplomatic relations with the
breakaway region. The Convention's own real wording is specifically
about "capacity" - a theoretical ability to conduct relations - so a
region could arguably still possess this capacity even while no other
state chooses to exercise it with them. But in practice, if literally
no other state will engage diplomatically, the region cannot actually
demonstrate that capacity being genuinely realized, which is exactly
why real-world statehood disputes so often center on this fourth
criterion specifically rather than the more straightforwardly
verifiable first three (a population and territory can usually be
observed directly; government function can usually be observed
directly; but "capacity for relations" depends partly on other actors'
own choices, not on the region alone).

ANSWER: The capacity to enter into relations with other states is the
criterion in doubt - the region appears to satisfy the other three
(population, territory, government) on the facts given, but with no
other country willing to establish diplomatic relations, its real,
practical capacity for external relations remains unrealized and
contested, which is exactly why real-world recognition disputes
typically center on this fourth criterion.

WHY THIS WORKS AS AN ANSWER
------------------------------
This correctly isolates the one criterion the scenario's own facts
leave unresolved, distinguishing it from the other three that are
explicitly satisfied, and explains why this particular criterion is
genuinely harder to verify unilaterally than the others.
