Should Canada pull her troops and tanks out of Afghanistan?

i feel canada should stay till the task is compleated they are helping the USA in giving a country its freedom back. The taliban is a group that needs to be wiped off the planet all they did was opress their people and give their people no freedom and they were a breeding ground for terrorists. You are correct thats the point of NATO when a nato member needs help the other members should be ready to help because i know the USA would help canada in a second if they ever needed it.
