I don’t think Argentina is in any position to attack the Falklands.... but there are a couple of Chilean islands that are also ‘disputed’.
I think it is more likely that this is just noise for domestic reasons (failing socialists need distrations).
That would be even more stupid then their challenging the UK.
Chile has an extremely professional military. They will mop up the gas station attendants that Argentina calls their "army" and pick their teeth with their bones.
This time they might take back some territory that belonged to Chile a couple of centuries back.
OTOH Argentina and Chile are now best friends.
The Gripping Hand, Chile has a similar sized military to Argentina, but a couple of decades more modern. Not an enemy Argentina needs
The Brits do not have a carrier capable of carrying fighters any more...they trashed or sold all of their Harriers. They could cross deck US Marine Harriers...but I doubt Obama would approve any such support.
The Daunbtless is good, but carriers only 48 missiles before a reload is necessary. She could be overwhelmed with aircraft and missiles attacking her. The Brits need to dispatch another squardron or two of Eurofighter Typhoon aircraft to the Island to augment the four or five planes they have there now, and they could quickly use the HMS Ocean LHD to reinforce the Island with hundreds of Marines and armor and artillery.
That’s what they could do if the Argentines do not try to pre-empt it. Last time it was the surprise nature of it that allowed the Argentines to get on the island. This time the Brits already have a Offshore Patrol Vessel, the four or five fighters and a detachment of soldiers to keep from being surprised.
If they send the Dauntless, the Ocean and some more fighters, they should be ok.
But, outside of that, the UK is not nearly in as good a position as it used to be naval wise.
If Brazil, Venesuela, Cuba and Argentina all teamed up, the Brits would have a hard go of it.
The issue here is the oil they have found around the islands.
You can bet the Brits already have one or two nuclear attack subs there and that will keep the Argentines from using a naval force to try and invade...it would have to be air assault.
With the Dauntless and the Ocean and her escorts, and a beefed up 2-3 squadrons of Typhoons, I do not think the Argentines and their allies could do it.
We have our own socialist here who needs a boost. I bet the Iranian Show is scheduled for Summer in good time to re-elect a War President but without sufficient pre-election time for the pro-Sunni Caliphate and anti Israel goals of the war to be yet obvious.
