Aside from all the arguments about relative capabilities, the key issue is one of political will. There probably isn't the same will in Argentina to repeat the decisions of 1982 but the worrying fact is in the UK we are seeing that period played out all over again.
Put simply, with forces over-commited in a war Brown inherited and frankly wishes he didn't have, a govt who really wishes the military were something they didn't have to consider and an economic crisis of huge magnitude, there is no chance of us doing anything sensible as pre-emptive action. Unless we take the national eye off the economic ball by invading somehwere............
And as for the Jeremy Kyle Show fodder us tax payers fund at the expense of a genuine contribution to national well being, perhaps if we rehoused them in the FI the Argies would think twice anyway!! Better yet, they could have them.
