I struggle with this issue, too. Are we doing any good? Are we doing more harm than good? I wish I knew the answer. I'm a pacifist by nature, but human nature and the politics of our world are not that simple.
But those issues are irrelevant to what is. Our troops are there, and they are demonstrating incredible courage just in being there, in that political climate.
I can't but admire the members of BR for agreeing to go, whether or not they agree personally with Canada's presence in Afghanistan.
Here's a verse from Greg's song Alaska, from Aphrodite Rose. I think the last line sums it all up perfectly.
For these men of high esteem
And little valour
In a land where you can buy
Or sell an election
These good christian men
Need their armies to protect them
And everybody knows a soldier just wants to go home
