Answer Key

Question 1

C. An unwelcome or unacceptable person

Declaring someone persona non grata is the formal diplomatic way to expel them from the country — one of the most serious steps a government can take short of breaking off relations entirely.

Question 2

A. An easing of tension and hostility

Détente is most famously associated with the 1970s thaw in US-Soviet relations, championed by President Nixon and Secretary of State Henry Kissinger — a welcome cooling of Cold War tensions.

Question 3

B. An official public statement summarizing the meeting's results

A communiqué (French for "something communicated") is the formal press release of diplomacy — it tells the world what leaders agreed on, disagreed about, or discussed at their meeting.

Question 4

D. Being arrested or prosecuted under the host country's laws

Diplomatic immunity, codified in the 1961 Vienna Convention on Diplomatic Relations, means a foreign diplomat cannot be arrested, sued, or tried in the country where they are serving.

Question 5

C. A final set of demands whose rejection will lead to serious consequences

An ultimatum leaves no room for further negotiation — a famous example is the Austro-Hungarian ultimatum to Serbia in July 1914, whose rejection helped trigger the First World War.

Question 6

B. A military officer assigned to an embassy to handle defense and intelligence matters

Military attachés are uniformed officers officially assigned to embassies, where they observe and report on the host country's armed forces — a role fully recognized under international law.

Question 7

A. Runs the embassy when the ambassador is absent or the post is vacant

The chargé d'affaires (French for "one charged with affairs") becomes the acting head of a diplomatic mission when the ambassador is away or when no ambassador has yet been appointed to the post.

Question 8

D. Imposing penalties — such as trade restrictions or asset freezes — to pressure the country to change its behavior

Sanctions are a diplomatic tool designed to change a government's behavior without resorting to war — they can target an entire economy or be "targeted" at specific individuals or companies responsible for bad conduct.

Question 9

C. Neither the American nor Soviet bloc — they stayed independent of both superpowers

The Non-Aligned Movement was founded in 1961 by leaders including India's Nehru, Egypt's Nasser, and Yugoslavia's Tito, who wanted to avoid being pulled into either side of the US-Soviet rivalry.

Question 10

B. The restoration of friendly relations after a period of hostility

Rapprochement (French for "coming together again") is one of diplomacy's most welcome developments — a famous example is the US-China rapprochement of 1972, when President Nixon made his historic visit to Beijing.

Question 11

A. An act or event used to justify going to war

Casus belli is Latin for an "occasion" or "case" for war — governments have long used the concept to explain why they felt justified in taking military action, from the sinking of the USS Maine in 1898 to many conflicts since.

Question 12

D. A brief written summary of a diplomatic meeting or a government's official position on an issue

The aide-mémoire (French for "memory aid") is one of the most common tools in the diplomat's kit — it ensures that both parties leave a meeting with the same understanding of what was said and agreed upon.

Question 13

B. Making a formal diplomatic approach — often to register concern or protest

A démarche (French for "step") is a formal diplomatic move, often delivered by summoning an ambassador to the foreign ministry — a way of registering displeasure or concern without the drastic step of breaking off relations.

Question 14

C. A temporary practical arrangement that lets disagreeing parties work together anyway

Modus vivendi is Latin for "way of living" — in diplomacy it means two parties who cannot fully agree have at least found a workable arrangement that lets them coexist without constant friction or conflict.

Question 15

A. The rules of ceremony and precedence — such as seating order at state dinners and how officials are formally addressed

Protocol officers make sure heads of state are greeted in the correct order, flags are displayed properly, and no one is accidentally offended — small ceremonial details that can carry enormous symbolic weight in international relations.
