I will do anything to protect this 
country where my sister lives.
سأقوم بأيّ شيء لحماية هذه البلاد
.الّتي تعيش أختي فيها
Ich würde alles tun, um das Land
zu beschützen, in dem sie lebt.
Haré cualquier cosa para proteger
el país donde vive mi hermana.
Haré cualquier cosa para proteger
el país donde vive mi hermana.
Je suis prêt à tout
pour protéger le pays où elle vit.
Sono disposto a fare qualunque cosa 
per proteggere il Paese in cui lei vive.
E farei de tudo para proteger 
este país, onde minha irmã mora.
И для того, чтобы защитить страну,
где она живёт, — я готов на всё.
