Like it or not Ladies and Gentlemen, there is no doubt that the UK had "tacit" assistance from the U.S. during the Falklands War.
This may not have come as direct military logistical help, but given the tight political relationship between Thatcher and Regan at the time, intelligence and political pressure would have been made available at every opportunity.
Go back to the time of the conflict and examine how many countries publicly supported Argentina, there were very few (aside from the cowardly communists and cowardly Frogs, who, at that time, were quite happy to supply the Argies with missiles and ammo'
).
I don't support everything they do, but there are very few conflicts which our cousins across the pond don't help us out with.
