Aqui No Sera Lyrics
Vamos milicianos en lucha y canción
Tu Salvadoreño pequeño gigante
Enséñala a todos aquí no será
Tu Salvadoreño pequeño gigante
Enséñala a todos aquí no será
Aquí no será como un Vietnam
La American entera, no permitirá
Otra intervención en El Salvador

This song is a political cry for action. The music is so beautiful and relaxing but the lyrics are strong and provoking.

Yes, it must be about the military action of the U.S. in El Salvador in the 80's. As a Salvadoran, it's great to find a new song that speaks of my country.

There are some minor errors on the lyrics. It should be:
Desde las Malvinas hasta la misión Vamos milicianos en lucha y canción Tu salvadoreño, pequeño gigante Enséñale a todos, aquà no será Tu salvadoreño pequeño gigante Enséñale a todos aquà no será
Aquà no será fácil ocasión Aquà no será tan solo un Vietnam La América entera, no permitirá Otra intervención en El Salvador
(Note: In the lyrics, América refers to "North and South America", not the US. Latin Americans believe in it as one big continent, and they don't usually call people hailing from the US as "Americans". Just so you know...)
