Greenland and Denmark have formed a united front to face down U.S. President Donald Trump, momentarily setting aside the troubled history between them.

The Arctic island, a Danish colony for three centuries, still has a complicated relationship with Denmark, which now rules it as an autonomous territory.

Greenland¡¯s main political parties all want independence, but disagree on how exactly to get there. Trump¡¯s designs on the island led them to forge a coalition government in March last year.
