There's a snowball chance in hell for another atempt to take the islands by force.
Argentina was in it's best military shape when they tried last time and the island had almost zero defences.
Now things are a lot different. Trying to invade now would create a lot of casualties and the defenses on the island would most likely be able to hold the invasion, until help arives.

Very different picture. I doubt the Argentinians are willing to take the kind of losses they would suffer.
