We couldn't do the Falklands again now.
We couldn't have liberated Kuwait without the US anyway.
Former Yugoslavia did not require a Typhoon, a main battle tank nor a large carrier.
Saddam was overthrown by the US with the UK helping here and there.
I'm not talking about disbanding the military nor cutting the expenditure. I am talking about hard choices, fixed budgets and the here&now.
