I believe the geopolitical indicators we've had since at least 2008 have shown us that we are moving into an international area where the use of force at great power levels is becoming an increasing possibility.
What I was talking about at the Battle of the Atlantic event is the manner in which we can no longer pretend that the end of history has basically eliminated the possibility of war between great powers that will include Canada. Therefore, Canada needs to get out of this mindset that simply doing enough in terms of what our allies say, such as meeting 2% of GDP in terms of our defence...is no longer good enough. We have to be thinking in terms of what we need for military capabilities to actually deter, and to be prepared to fight if that deterrence breaks down.
In the international geopolitical environment, we look at the directions the Chinese, Russians and even Americans have taken, which have given the probability of conflict a huge increase, unfortunately.
