Four hypothetical strike cruisers in the Falklands War

What if Britain suddenly received four strike cruisers after Argentina invaded the Falklands?

Britain would keep useful ships that proved themselves, while other naval powers would probably seek comparable units.

The war would end too quickly for Britain to build four strike cruisers in response to the invasion. The scenario therefore depends on the ships appearing already available. If they were viable and used successfully, both the navy and government would keep them. The anticipated foreign responses include additional Soviet Kirovs and comparable American and French ships.
