A small addition to the highlights above (my bold):
There is a clear message here – as Defence is always saying ‘with a bit more cash we could do the following’, it now has a chance to follow through on this.
While this may be painful to hear, the message is a simple one – don’t screw this up. Getting this wrong could have very painful long term consequences for Defence, and enrage a PM and Chancellor who have taken a lot of political risk to deliver this for the MOD.
