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 some foreign country -- you're going to trade off something, either money or time, convenience, capabilities, maybe fundamental liberties.
不管是个人决定 比如是否给家里装一个防盗器 或者国家的决策，比如去侵略哪个国家 你都要去交换， 不管是金钱、时间、便利、能力， 还可能是基本自由权。
