Amen.
I was in the UK during the Falklands War in 1982 and as a Canadian it was embarrassing to see the blatant jingoism on the street and in the tabloids ("gonna get me an Argie!").
This was a 'war we can win' just like the US invasion of Grenada around the same time; a war to increase support of the government in power.

Grenada- Wasn't that the last war the US won?
Oh- I forgot about Panama-
It was a distraction for the press, to get the Marine Corp Barracks Bombing in Lebanon off the front page--
And the sheeple went along.

You seem to have forgotten that the Argentines actually invaded the Falklands. Forcibly. Armed with weapons. You also seem to have forgotten that the Argentines at the time were in thrall to a military dictatorship (which had 'disappeared' 10-20,000 of its own people). The Falkland locals did not ask them to invade. At the time (and now) 99% of the population wanted to remain linked to the UK.
As for it being a 'war we can win' - I suggest you study the campaign in detail; the UK forces were operating at the end of a 5000 mile seaborne supply link which was extremely tenuous (with aircover provided by less than 30 Harrier jump jets), and the Argentine military (particularly its aviation) were no Grenadian militia (I wonder if you have heard of the word Exocet?). The loss of one aircraft carrier would have doomed the enterprise. Considering the difficulties with logistics (at one point the Argentines knocked out 90% of the UK forces heavy lifting helicopter force) it was really an immense gamble to even undertake the mission.
Still, hell why let a few inconvenient facts get in the way of your political bias.......

absolutely right

the entire argument seems to be that Argentina is close by therefore they have the right to invade

and as to easy - this was an incredible achievement that few militaries in the world could have matched at the time and the Argentine army was a serious foe
