Perhaps our American cousins regret leaving the British colonies.
"British traditions such as the monarchy were rejected by the U.S. Constitution, but many English common law traditions such as the right to keep and bear arms, habeas corpus, jury trials, and various other civil liberties were adopted in the United States. Significant elements of English common law prior to 1776 still remain in effect in many jurisdictions in the United States, because they have never been rejected by American courts or legislatures.[5] Approximately one third of the world's population (approximately 2.3 billion people) live in common law jurisdictions or in systems mixed with civil law."
