Part of the recognition of the real strengthening of core central strategic assets that has happened in the 15 years is important.
When Canada signed on to the R2P protocols--the responsibility to protect--some argued that there is a codicil to that: the ability to project. You need the ability to move if you're going to have influence to move resources. The strategic centre was perhaps undeveloped at the time, so we didn't have the necessary forms of heavy lift; we didn't have good secure strategic communications; we didn't necessarily have the intelligence architecture and the national command and control architecture we have now.
Those are really valuable improvements, largely invisible to big swathes of the armed forces, but I think they are enduring characteristics and something to think about, and how the centre thinks. You have an army, an air force, and a navy. There are national requirements larger than those three.
