KJM:
The Falklands War brought a lot of victims to both side of a stupid conflict but, besides giving Lady Thatcher the boost she needed, it gave the kick of death to a brutal military dictatorship in Argentina and most probably added to the resolve of Brazilian military in restoration of democracy.
Just a quick comment:
She didn't start the war. Even if she withdrew military assets, Argentina is the country who decided to invade and conquer the Falklands. Now maybe if everyone on those islands wanted to join Argentina then there would have been justifications, but the inhabitants of those islands are British and want to remain so.
A while ago I looked at who has the better claim to those islands. They were claimed by the Spanish and the British, but the Spanish abandoned them during the Age of the Land Grab... oops, I meant Age of Exploration and the British didn't. That basically means the Spanish claim disappeared, and with the Spanish giving up that claim the successor state of Argentina couldn't inherit it. That, added to the people who live there being happy with the British claim, means it's British....
Unless someone conquers it from them. Right of Arms trumps Right of Settlement.
