> The Falklands can be defended against Argentina.
Barely. The Falklands was touch and go, Britain was only one or two Exocets away from losing. To bomb the runway at Port Stanley, the Vulcan bombers required in flight refuelling 4 times. And the tankers that refuelled them had to be in flight refuelled themselves. The whole thing was cobbled together with string and duct tape and it only just worked.
