Can you give us a hint?
Worse than giving almost all of "palestine" to the muslims when it was supposed to be 50-50?
One example, the Pakistan/India division was made without any consideration of where the Hindu and Muslim populations lived, and without sufficient notice to allow for orderly relocation. As a result, millions of people were uprooted, at least hundreds of thousands, perhaps millions, died in the upheaval as a result. Many more innocent deaths than have occurred with the Palestine debacle.
