Where has our sense of duty gone?

Most Canadians oppose military role in Afghanistan

The results of these polls, if taken seriously, are quite distressing; since when has soldiers deployed to foreign fields, soldiers of free countries, supporting their own citizens freedom while at the same time spreading the same freedom, been a bad thing?
Perhaps our soldiers are getting tired, but this is not their fault, they have exerted tremendous energy doing their jobs and they cannot be blamed for the neglect they had received in the decades before this mission.
But even that is not a reason we should oppose them being present in Afghanistan, merely a reason we need to support them better and give them some more rest.

The saying 'No man is an island' could easily be applicable to almost any state on this globe, we a duty to our citizens and to our allies. The freedoms we enjoy in Canada, the same ones I might mention we are giving up so easily, did not just miraculously appear out of nowhere. It took the blood, sweat, and lives of many Britons and Canadians to achieve, and this we should not forget so quickly.
If these heroes offer to die for our sake, for the sake of our children and our children's children, should we refuse them that? Should we spare any effort to give them the best equipment and training so they can perhaps, even as they offer their lives as a sacrifice, live to see another sunrise and cherish what is undoubtedly something much more meaningful than it was before?
