I understand what you're saying, but I have to wonder why it is American convoys are getting into southern Lebanon and managing to evacuate US or Australian nationals. Why is Canada unable to reach an agreement with Israel while at the same time, the US has managed to do so and send in convoys?
I'm personally aware of two youths 12 and 14 years of age who were evacuated by American convoys from southern Lebanon while bombs were raining down on the region. You're correct in saying that people cannot easily be contacted. They cannot emerge from their underground hiding places because the bombs are falling. Summing up, I think Canada could follow the lead of the United States and go in and rescue these people.
