CG, if we lose the Islands, we can't even begin to think about taking them back. the loss of carrier aviation - and i'm talking generally, not specifically about CVS/GR9 - means we have no capability to threaten an Argentine garrison on the Islands.
they wouldn't need to spend billions to keep them, they would be as untouched by UK forces as if they were on the far-saide of the moon. the monetary cost to Kirchner of eternal political popularity and having every town square in Argentina named after her would litterally be however much it cost to re-write the signposts in Stanley in Spanish.
thats it.
we should take that into consideration - as well as remembering that before the loss of CVS/GR9, part of the deterent to Argentina came in the shape of our (probable) ability to retake them should the Argentines manage a successful invasion/seige. that has now gone, yet the force on the Islands remains the same.
you mentioned the stupidity of politicians?
