I think the terms 'America / Presidents can fall' refers to how first world nations like the West can fall under terms of devastating war, with 'The Heat' referring to a nuclear war happening beforehand.
The lines 'Paint me a picture, towers in sand/bodies in sand' talks about the life before the war. As said before, the singer 'Dies' figuratively because of the things he sees and the memories he has after the war.
Overall it's a song about the aftermath of a devastating war.
