BVI - British Virgin Islands So, Britain sent out the troops, which seems reasonable considering it is a British island, with British corporations located on Tortola, & several billionaires, ie. Branson is a billionaire & helped coordinate action. USVI - US Virgin Islands. An American island.
St Martin - half the island is Dutch,  half is French Oh, it's a Dutch & French island.
See the differences? None of these islands are Canadian. That explains why Canadian troops were not deployed. Airports were severely damaged/destroyed, so flights were limited, thus govts of these islands must pick & choose which flights can land. That adds to the problems of getting Cdn flts in after Irma. It is hurricane season, common sense says don't travel to Caribbean/Mexico at this time. If you do, and you demand your government rescue you, just like Stars Ambulance, expect an Invoice for the cost. It shouldn't be taxpayers paying for others stupidity.
