What is the 'rain' in the title mean ?

Its the title of a Vietnam war protest song by Creedence Clearwater Revival.
The movie was going to be called Dog Soldiers, (after the book its based on)
but when the producers got the rights to use this song, they changed the title to Who'll Stop The Rain. When interviewed by Rolling Stone magazine, John Fogerty was asked, "Does 'Who'll Stop The Rain' contain lyrically specific meanings besides the symbolic dimension?" His response: "Certainly, I was talking about Washington when I wrote the song, but I remember bringing the master version of the song home and playing it. My son Josh was four years old at the time, and after he heard it, he said, 'Daddy stop the rain.' And my wife and I looked at each other and said, 'Well, not quite.'


"Mr Narrator, This is Bob Dylan to me..."

i guess you can say the {rain} meaning all the tears we the parents cried for there children who were killed in vietnam .

I got the sense that the "rain" was the trouble the characters were descending into. It's like a storm, and they want the clouds to break.

But am open to other theories, of course.

Holy *beep* The "rain" meant the rain of bombs on Vietnam. Watch/read some basic history guys.

CORRECTION: The song is not about Vietnam (though it is from the Vietnam/Woodstock era). Look at the actual lyrics. It appears to be more about human unhappiness in general, and our desire to escape it (which is what is happening in the film).

It references philosophers and politicians like FDR trying to elevate people from that unhappiness -- along with people trying to escape it through events like Woodstock. But utlimately, it implies, no outside force can eliminate it for you, you have to deal with it / resolve it on your own.

(Lyrics at the bottom.)

Note that CCR also wrote "Have you ever seen the Rain", where Rain is again a metaphor for human unhappiness. Rain has traditionally been used as a symbol for this, in many other songs.

Long as I remember the rain been comin' down
Clouds of mystery pourin' confusion on the ground
Good men through the ages tryin' to find the sun
And I wonder, still I wonder who'll stop the rain

I went down Virginia seekin' shelter from the storm
Caught up in the fable, I watched the tower grow
Five year plans and new deals wrapped in golden chains
And I wonder, still I wonder who'll stop the rain

Heard the singers playin', how we cheered for more
The crowd had rushed together tryin' to keep warm
Still the rain kept pourin', fallin' on my ears
And I wonder, still I wonder who'll stop the rain
