Leaked email claims US will withdraw support to UK on Falkland Islands, Rubio replies

A leaked Pentagon email has claimed that US could withdraw support for Britain’s sovereignty of the Falkland Islands, over which UK and Argentina went to war in 1982. US Secretary of State Marco Rubio called it "just an email with some ideas", terming the reaction to it as "overexcited". US could withdraw support as UK didn't participate in Iran war.
