LYRICS

Thirty Seconds To Mars - This Is War

A warning to the prophet,
The liar, the honest,
This is war.

To the leader, the pariah,
The victor, the messiah,
This is war.

It's the moment of truth, and the moment to lie,
The moment to live and the moment to die,
The moment to fight, the moment to fight,
To fight, to fight, to fight!

To the right, To the left
We will fight to the death!
To the edge of the earth
It's a brave new world
From the last to the first

To the right, To the left
We will fight to the death!
To the edge of the earth
It's a brave new world
It's a brave new world
It's a brave new world!

I do believe in the light
Raise your hands into the sky
The fight is done, the war is won
Lift your hands toward the sun
Toward the sun
Toward the sun
Toward the sun
The war is won

To the right, To the left
We will fight to the death!
To the edge of the earth
It's a brave new world
From the last to the first

To the right, To the left
We will fight to the death!
To the edge of the earth
It's a brave new world
It's a brave new world
