No matter what difficulties we face...
...مهما واجهنا من صعاب
Egal, was uns auch widerfahren wird …
Sin importar qué problemas
se nos presenten
Por muchos problemas
que nos salgan al paso,
Et ce, qu’importent les difficultés…
Non importa 
quali difficoltà dovremo affrontare...
independentemente das
dificuldades que enfrentamos
С чем бы мы ни столкнулись…
