weemonkey,
Be VERY careful what you wish for!
If the review was scoped as you suggest, and merely focuses the UK armed forces on home defence, you would end up with maybe 4 Typhoon AD squadrons, 1 wedgetail AEW Sqn, 1 P-8A squadron, a couple of radar stations, the SAS, a few ceremonial Guards regiments, a few OPV's and that would be about it.
