If there's a hill the UK is prepared to die on this is it, 99.9 percent of Falkland Islanders voted to remain part of the UK in a UN observed open election subsequent to the UK retaining control of the islands. Argentina has never maintained any form of civilian population there in nearly 150 years, they want the oil and fishing rights.

5 billion barrels of oil and access to Antarctican minerals says try it and find out. UK has a spiffy new aircraft carrier the Tories would love to send to divert attention from their abject failure to govern

So if Argentina gains votes at the current rate, 0.1 percent per thirty years they will hold a majority in 6000 years.

Try it and find out.

The military situation of Argentina and China aren't exactly the same.
