The Wormholy Land

The official name of the technology is Geographic Phase Displacement, but it’s marketed as Phasics.
Got a land dispute? Just set up a Phasics engine, set the boundaries of the field, and now both parties can occupy the region at the same time.
The Nobel Prize for Physics went to its inventor, and then three years later the Peace Prize went to resolution of the ancient conflict over the Temple Mount and Haram Al-Sharif.
Phasics engines were spread throughout the territory, and refugees hopefully and joyously poured into the parallel Al-Quds pocket-reality.
Problem solved.
So, why isn’t the terrorism stopping?
