222 out of 239 years according to this:
http://www.globalresearch.ca/america-has-been-at-war-93-of-the-time-222-out-of-239-years-since-1776/5565946
So, 21 years not at war with someone.
Not sure about the UK.
Marvellous, isn't it?

The 222 years thing is very much open to interpretation. If the US were known to use military personnel abroad in a year, that was deemed as being at war in that research.
If I am going to be really pedantic, war is a legal status and the US have only technically been at war a handful of times.
Edit: The only formally declared US wars were 1812, Spanish-American, Mexican-American, WWI, and WWII.
'peacetime'.
Strange use of the word peacetime. I'm fairly certain I read an article, before the Iraq War, that showed that there was scarcely a month let alone a year when either UK or US troops weren't on active service somewhere, from 1945 onwards,
and,
that was before you accounted for covert operations or 'local' activities like Ulster.
