Would Argentine fighter purchases lead to Falklands reinforcement?

Would the Falklands garrison be reinforced if Argentina bought J-10s or F-16s in large numbers?

Probably, if the purchases actually happened; announcements alone would not establish the need.

Reinforcement is considered probable if Argentina actually buys J-10s or F-16s in large numbers. The answer makes that response contingent on a real acquisition. Announcements and discussion of a purchase are treated as insufficient evidence that the capability has changed.
