I don't like commenting on world events on this blog because I would imagine most people hear enough about them from other sources. However, the recent loss of Ukrainian International Airways Flight 752 from Tehran is an exception because, as Alex Usher notes, many of the passengers were en route to Canadian universities and research institutions. "All day Wednesday and Thursday, stories poured in from across Canada. Thousands of hearts breaking in a dozen cities across six provinces. So many good people, so many dear friends….and just so, so much talent. Gone, in an instant." This was our community that was hurt in a conflict we had nothing to do with, a community we share with our brothers and sisters in Iran and around the world. To the leaders of the countries involved, I can only say that it is long past time you made peace.
