Britain's last two territorial conflicts involved the Falklands, and Icelandic fishing ships in the neighborhood of Rockall. I don't recall that third party assistance was required in either dispute, thank you very much.

The US the other hand is always asking for other countries to bail it out of some mess or other.

Did you miss the word "large"? And the UK required significant US assistance during the Falkland Islands war, so apparently you're quite ignorant about history.
