Youtube clip of Israeli oldie that starts in English with "you've got to believe"

There was an Israeli song popular in the 1970's - only thing I remember is that in English, it started something like:

You've got to believe
we can turn this world around
you've got to believe
there's a new world to be found
....
I've heard it before ...
so many time ....
...
You've got to believe
we can turn this world around

Can anyone ID the song and link to a youtube clip if there is one out there??

Thank you for whatever time you can afford to spend considering this matter.

Got it!! (thanks to my old friend Judy Benjamin, who used to "hang" at the Cafe Feenjon in NYC years ago):

I don't know if it is accurate or not.
