Without getting into hypothetical questions, it all depends on what type of threat we'd be facing. Right now, our best defence is making sure that we do not get into a World War III type of scenario, as Putin stated in his rhetoric, and making sure that we have the right communication and the right diplomacy to prevent that.
Having said that, we, as a nation, need to be mindful of how we're going to look at our own sovereignty, making sure that we have the right equipment moving forward. I hope that we will able to answer a lot of these questions after the defence review.
What types of capabilities are needed? I don't want to get into the exact details of what type of equipment we need to buy. Capability is going to be the key. How are we going to integrate? How is our command structure going to continue, in terms of a relationship? Where do we need to invest in technologies, and where do we need to invest in our people to make sure that we have the right defensive posture to prevent any type of attack?
