Dreadnoughts
Perhaps a comparison could be made to the early 1900's when the nation cried out for more dreadnoughts than the government had funded. If only we can raise peoples awareness of what the future funding of the MoD will mean, in terms they can identify with, ie:
1) cannot do a falklands (Task group size, attrition and sustainability)
2) cannot afford to launch our own air attack without US support (specialist support, quantity of tanking etc)
3) cannot get the army to where they need to be and support them. (heavy lift, RW support)
Ma'am, your trusted servants need you more than ever!
