<p>World politics can be understood, simply, as Who Gets What, Where and How? (globally) to borrow a title from a famous old book by Harold Lasswell. International relations are a critical level in that business of determining who gets what across the world. Decisive things take place at the international level, and they directly or indirectly affect all our lives: war, trade, and the provision (or not) of human rights for example. This book covers everything you know to better understand the world you live in.</p>
