Can You Relate this All American Rejects song to War?

Question

Can someone please tell me how the all american rejects song The Last Song can be related to war? The lyrics are below...

This may be the last thing that i write for long
can you hear me smiling when i sing this song
...for you
...and only you

As i leave will you be someone to say goodbye
as i leave will you be someone to wipe your eye
a foot is out the door and you cant stop me now

you wanted the best, it wasnt me
will you give it back
well i'll take a lead
when theres no more room to make it grow

see you again
pretend that your naive
is this what you want
is this what you need
how do you end up lettin me know

as i go
remember all the simple things
you've known
my mind is just still clutchin
i still hope
that you will miss me when i am gone
this is the last song

your heart start breakin as the year is gone
the dreams beginning and the time rolls on
seems so surreal
now i sing it

somehow i knew that it would be this way
somehow i knew that it would slowly fade
and now i am gone
destroyed and so mad now

you wanted the best, it wasnt me
will you give it back
well i'll take a lead
when theres no more room to make it grow

see you again
pretend that your naive
is this what you want
is this what you need
how do you end up lettin me know

as i go
remember all the simple things
you've known
my mind is just still clutchin
i still hope
that you will miss me when i am gone
this is the last song

will you leave me now
you'll find the way somehow
you wanted to
i wanted to

as i go
remember all the simple things
you've known
my mind is just still clutchin
i still hope
that you will miss me when i am gone
this is the last song (repeat 2x)
