Is anybody really believing that Argentina is going to wage another war with the UK over the Falklands, really???
This is not 1982 junta ruled Argentina any more, sure there are still a lot of bad feelings but I don't believe their is any support for such an "adventure" among the Argentinian population, let alone a real capability from the Argentinian forces.
4 Typhoons might be a limited force but it would be more than sufficient (combined with SAM weapons) to hold of long enough for reinforcements to arrive ,additional Typhoons/Tornado's, Tankers,AWACS, Transport with more weapons and troops can probably be sent within 48 hours, I guess.
