That was the same strategy of the Mumbai and the Westgate Mall attackers; they deliberately target foreigners messing with their Islamic paradise.
I have never visited a Muslim country (or one where more than 10% of the population is Muslim), and never will.
It makes a bigger impression that way, making people in Western countries more likely to accept dhimmitude.
I guess there was no obvious Jewish center, like the Chabad house in Bombay, available, or perhaps this group of "youths" wasn't as sophisticated.
You are very wise.
