What’s that ‘old saying’ ?
Something ‘bout all plans are B*S*t when the first shots are fired?! .... or somp’in’.
Of course “we know more now”.... that’s the way life & war is....
Dumb question asked and answered, eh?
:)
But that's no excuse for not having a plan...or contingency plans...or listening to a guy (Rumsfeld) who claims he knows more than those who have succeeded in anti-insurgency campaigns in the past (Brits).
