爱国如家的意思是像爱我们的家一样爱我们的国。可以翻译为love ones country the same way one loves ones own family。

其中隐含着如此的观念:热爱祖国的人都不分彼此,好似一家人,每一个人都像爱我们的家一样爱国爱民(all those who love their motherland are intimately bound together as if they were from the same family, so they should love their country and its people in the same way they love their families)。

例子:

烈士之爱国也如家。

A person with noble aspiration1 loves his country the way he does his family.
