Whether this is a personal decision — whether you're going to install a burglar alarm in your home — or a national decision, where you're going to invade a foreign country — you're going to trade off something: money or time, convenience, capabilities, maybe fundamental liberties.
Sea esta es una decisión personal -si van a instalar una alarma antirrobo en su hogar- o una decisión nacional -si van a invadir otro país- van a sacrificar algo, ya sea dinero o tiempo, comodidad, capacidad, quizás libertades fundamentales.
