Law & Government

Law, politics, policy and international affairs

A track running along an international border between two countries, marked only by a change in the landscape.

Annexation

In simple terms Annexation is a state declaring that territory it holds by force is now legally its own.

BRICS

In simple terms BRICS is a grouping of major emerging economies that meet to coordinate on trade, finance, security and development. The name began as an investment label.

Coalition government

In simple terms A coalition government is a government formed jointly by more than one political party. No single party runs it alone.

Cruise missile

Export controls

In simple terms Export controls are laws that decide what a country will let leave its territory, and who may receive it.

The European

Naval blockade

In simple terms A naval blockade is a warring state sealing off an enemy coast or ports by force, so that ships cannot get in or out. It is a method of warfare rather than a trade measure, and that difference decides which rules apply to it. A blockading navy stops ships from countries that
