Tell Argentina to go screw, thay got whupped by a small expiditionary force last time. Despite being marred with catastrophes, the Brits still won.
Besides the Brits got one thing they don't. The USA as an ally. Not that they need us to kick around some 2 bit far leftist dictatorship looking to kiss up to Hugo Chavez, considering they did it last time with a few carriers and a small contingent of troops.
I read alot about the 82 Falklands conflict, and from the info I came across, the Brits had no chance. Fighting a land based airforce with limited resources, losing the helos, forcing the troops to land on the other side of the island, and fight thier way across it.
All the while coming under attack from mainland based air attacks with antiship missiles. The entire operation was well run, and well led.
(Note I called it the Falklands and not Malvinas)
