This idea was part of the motivation Dr. Zamenhof had in creating Esperanto. He felt that if everyone spoke it, in addition to whatever other languages they spoke, then there might be a greater level of understanding between peoples and fewer conflicts. I studied Esperanto a bit and found it interesting. But as to whether it would accomplish Zamenhof's goal, I'm dubious. It might not help, but probably wouldn't hurt.
